The document discusses network emergence and genetic evolution. It provides examples of emergence in various domains including social science, physical science, and biology. Emergence occurs when new properties or behaviors arise from the interaction of parts that the parts do not exhibit on their own. The document also discusses open-loop emergence where a network absorbs energy and changes over time through the repeated application of micro-level rules, as well as genetic emergence where micro-rules are repeatedly applied to observe how a network evolves. Designer networks with a given degree sequence can be generated using algorithms like the Molloy-Reed algorithm.
We believe the quantum entanglement is caused by the very space itself, not by any particles, and thus not bounded by the speed of light, so is the gravity, we stand at fireworks side.

Is There A Contradiction In The Physics Book?Gerges francis
I claim there's a contradiction in the physics book, let's explain it:
Lorentz Transformations Effect
Lorentz Transformations tell us that, Particle data is created relative to its motion, basically because Particle mass and length are changed because of particle high velocity motion…
If Lorentz length contraction is a real effect on particle own nature or just illusion of measurements! This question we have discussed before- and we have found that- Lorentz Length Contraction is a real phenomenon effects on Particle own nature similar to Particle mass increasing as a result of high velocity motion
The previous consideration we have adopted for the next reasons:
(1) The measurements show this contraction and in physics what's measured is what's real
(2) If we consider the length contraction is an illusion of measurements, that tells Particle properties correct definition is found when no difference in motions velocities between me and this particle, which supposes that I'm The Universe Reference Point – that's similar to a person looks at mirror – which pushes us to refuse the claim that the contraction is an illusion of measurement
Conclusion
I. Lorentz Length Contraction is a real phenomenon effects on Particle own length
II. Particle Data is created relative to this particle motion
The last conclusion leads us to a contradiction with Newton mechanics
Newton had interpreted Planet motion based on the masses gravity between this planet and the sun – So Planet Mass is the reason of its motion
But Lorentz transformation tell us that – Particle Data (and mass) is created based on this particle Motion…!
i.e.
Planet Motion – according to Lorentz Transformation- must be the reason of Planet Mass – so Planet doesn't move by Masses Gravity – because planet mass is created depending on its motion which tells that Planet motion is found before any other planet data! So how does planet move?

Spontaneous creation of the universe ex nihil by maya lincoln and avi wasserJulio Banks
Questions regarding the formation of the Universe and ‘what was there ’ before it came to existence have
been of great interest to mankind at all times. Several suggestions have been presented during the ages –
mostly assuming a preliminary state prior to creation. Nevertheless, theories that require initial conditions
are not considered complete, since they lack an explanation of what created such conditions. We therefore
propose the ‘Creatio Ex Nihilo ’ (CEN) theory, aimed at describing the origin of the Universe from ‘nothing ’ in
information terms. The suggested framework does not require amendments to the laws of physics: but rather
provides a new scenario to the Universe initiation process, and from that point merges with state-of-the-art
cosmological models. The paper is aimed at providing a first step towards a more complete model of the
Universe creation – proving that creation Ex Nihilo is feasible. Further adjustments, elaborations, formalisms
and experiments are required to formulate and support the theory.

A introduction paper to some quantum concepts that steer us to the future of bio-functions, some quantum mathematical computations to consider. written August 2012, more to come...
A brief introduction to the subquantum regime, where the origination of all the observable events and processes of tour physical world can be found. Descending along the scale supplied by the divisibility of Quanta toward increasingly fine structures bearing fractional charges, down to the infinitesimal values where Information couples to space and time, we penetrate into a new, still barely explored reality, which nonetheless is supported by the laws of modern physics. We just begin understanding the properties of the physical vacuum, where entities displaying collective coherent behavior patterns are at the background of all the manifestation forms described by Quantum mechanics. We postulate that these understanding apply also to the synergetic mechanisms linking the human brain to processes that run in Informatic space, due to the morphogenetic blueprints responsible for its specially adapted structure for processing Informatic fields that are encountered along the biological entity’s worldline. The Information transfer is accomplished by subquantum flux vectors propagating at super-luminal velocities, velocities that theoretically are not prohibited beyond the application range of relativistic constraints. All these processes run under higher control instances embedded in Bohm’s super-implicated orders of Reality.

A Technique for Partially Solving a Family of Diffusion Problemsijtsrd
Our aim in this paper is to expose the interesting role played by differ integral specifically, semi derivatives and semi integrals in solving certain diffusion problems. Along with the wave equation and Laplace equation, the diffusion equation is one of the three fundamental partial differential equation of mathematical physics. I will not discuss convential solutions of the diffusion equation at all. These range from closed form solutions for very simple model problems to computer methods for approximating the concentration of the diffusing substance on a network of points. Such solutions are described extensively in the literature .My purpose, rather, is to expose a technique for partially solving a family of diffusion problems, a technique that leads to a compact equation which is first order partially and half order temporally. I shall show that, for semi finite systems initially at equilibrium, our semi differential equation leads to a relationship between the intensive variable and the flux at the boundary. Use of this relationship then obviates the need to solve the original diffusion equation in those problems for which this behavior at the boundary is of primary importance. I shall, in fact, freely make use of the general properties established for differ integral operators as if all my functions were differ integrable.

Electricity plays a special role in our lives and life. Equations of electron dynamics are nearly exact and apply from nuclear particles to stars. These Maxwell equations include a special term the displacement current (of vacuum). Displacement current allows electrical signals to propagate through space. Displacement current guarantees that current is exactly conserved from inside atoms to between stars, as long as current is defined as Maxwell did, as the entire source of the curl of the magnetic field. We show how the Bohm formulation of quantum mechanics allows easy definition of current. We show how conservation of current can be derived without mention of the polarization or dielectric properties of matter. Matter does not behave the way physicists of the 1800's thought it does with a single dielectric constant, a real positive number independent of everything. Charge moves in enormously complicated ways that cannot be described in that way, when studied on time scales important today for electronic technology and molecular biology. Life occurs in ionic solutions in which charge moves in response to forces not mentioned or described in the Maxwell equations, like convection and diffusion. Classical derivations of conservation of current involve classical treatments of dielectrics and polarization in nearly every textbook. Because real dielectrics do not behave that way, classical derivations of conservation of current are often distrusted or even ignored. We show that current is conserved exactly in any material no matter how complex the dielectric, polarization or conduction currents are. We believe models, simulations, and computations should conserve current on all scales, as accurately as possible, because physics conserves current that way. We believe models will be much more successful if they conserve current at every level of resolution, the way physics does.
Order, Chaos and the End of ReductionismJohn47Wind
The author presents a case against reductionism based on the emergence of chaos and order from underlying non-linear processes. Since all theories are mathematical, and based on an underlying premise of linearity, the author contends that there is no hope that science will succeed in creating a theory of everything that is complete. The controversial subject of life and evolution are explored, exposing the fallacy of a reductionist explanation, and offering a theory of order emerging from chaos as being the creative process of the universe, leading all the way up to consciousness. The essay concludes with the possibility that the three-dimensional universe is a fractal boundary that separates order and chaos in a higher dimension. The author discusses the work of Claude Shannon, Benoit Mandelbrot, Stephen Hawking, Carl Sagan, Albert Einstein, Erwin Schrodinger, Erik Verlinde, John Wheeler, Richard Maurice Bucke, Pierre Teilhard de Chardin, and others. This is a companion piece to the essay "Is Science Solving the Reality Riddle?"
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

2. EMERGENCE IN THE SCIENCES
the act or an instance of emerging.
In philosophy, systems theory, science, and art, emergence occurs when an entity is observed to
have properties its parts do not have on their own. These properties or behaviors emerge only
when the parts interact in a wider whole.
For example, smooth forward motion emerges when a bicycle and its rider interoperate, but
neither part can produce the behavior on their own. Emergence plays a central role in theories
of integrative levels and of complex systems.
Network science provides an abstract representation that is tailored to each discipline such as
engineering, physics, and biology.
3. Emergence in Social Science
In the social sciences, N is a set of actors, and L defines some relationship among actors. For example,
N may be the set of people who work together in an office, and L may be the lines on an organization
chart. Alternatively, N may be a set of people who have contracted a communicable disease from one
another, and L may be the interactions that led to contraction of the disease.
Emergence is more than a network’s transformation from an initial state to a final state. In the
physical and biological sciences, “emergence is the concept of some new phenomenon arising in a
system that wasn’t in the system’s specification to start with” (Standish, 2001). This definition refers
to the repeated application of microrules that result in unexpected macrostructure. For example, a
network’s degree sequence distribution is one way to characterize its macrostructure, while a link-
rewiring microrule might characterize its microstructure. There is no apparent connection between
the degree sequence distribution and a certain rule for linking node pairs. Still, some “new
phenomenon” might unexpectedly arise from repeated application of simple rewiring. For example,
the “new phenomenon arising” might be a scale-free degree sequence distribution arising from the
evolution, even though “scale-free structure” was not in the system’s initial specification. This “new
phenomenon” was unexpected because preferential attachment works at the local level while degree
sequence distribution is a global property.
4. Emergence in Physical Science
In the physical sciences, emergence is used to explain phenomena such as phase transition in
materials (gases cooling and changing to liquids, etc.) or Ising effects (magnetic polarization). In
thermodynamics, for example, emergence links largescale properties of matter to its microscale
states. Specifically, emergence links the temperature (large-scale property) of a block of ice to the
states of its molecules (microscale property); as water cools below its freezing point, individual
molecules change phase according to the microrules of physics, and the body of water changes from
liquid to solid (macroscale property). In network theory, this is equivalent to linking the classification
of a network to its entropy; a random network has greater entropy than does an equivalent regular
network. At what point does a random network become regular?
Emergence appears to stem from microbehavior at the atomic level (e.g., at the level of nodes and
links). It produces macroscale patterns from microscale rules. Often there is little or no obvious
connection between the micro- and macrolevels. This has led to the concept of hidden order—
unrecognized structure within a system (Holland, 1998). What appears to be chaos is actually
nonlinear behavior. Hidden order may be a matter of scale—what is impossible to recognize up close
becomes obvious when one steps back and views it at a distance. For example, a close-up view of a
painting may seem indistinguishable from random paint smears, but when viewed from a distance, is
easily recognized as the famous Mona Lisa. Is emergence simply a change in scaling factor?
5. Emergence in Biology
Emergence in networks and natural species of plants and animals is ratherobvious. In fact, some
contemporary biologists and natural historians claim that life itself is the product of
emergence—once called spontaneous generation. Life arose spontaneously over a long period
of time, by the repeated application of very small steps called mutations. Beginning with
inanimate chemicals and purely chemical processes, simple living organisms emerged through a
lengthy process of trial and error.
Biological emergence requires that we believe in increasing complexity at the expense of
diminishing entropy. On the application of each microstep (chemical reaction), randomness is
replaced by structure. Structure evolves through further application of microrules (absorption of
energy) toreplace simple structurewith more complex structure. At some point, the inanimate
structure becomes animate— complexity reachesthe level of a living organism. This process
continues, diversifies, and reaches higher levels of complex structure. Ultimately, the Darwinian
rules of evolution dominate, leading to the emergence of intelligence.
6. Simple-to-complex structure emergence has been demonstrated under controlled conditions,
but no one has demonstrated the emergence of life from nonlife. Organic substances have been
spontaneously generated from inorganic chemicals, but this is a far cry from the spontaneous
generation of a living organism from organic chemicals. As scientists, we must remain skeptical
of this theory.
7. GENETIC EVOLUTION
Open-loop emergence originates from within the network itself. The network absorbs energy
and forms new nodes and links or rearranges existing nodes and links. Emergence is dynamic—
microrules applied once per time step eventually lead to significant transformation of the
network. Over long expanses of time, the network reaches a final state, if the emergence is
convergent. If it is divergent, the network never reaches a final state and cycles through either a
finite or an infinite number of states. For example, suppose that a network with n nodes and m ,
n links adds one link at each timestep, until the network becomes complete. This convergent
process ends when the network reaches its final state with m¼(n(n21))/2 links. On the other
hand, a network that adds a new node and new link at each timestep, never reaches a final
state. Instead, it diverges, adding nodes and links without end.
Genetic emergence is simple—repeatedly apply microrules at each timestep and observe the
results. Does the network converge? In most cases, we conjecture that a certain pattern will
emerge after a sufficiently long time. Hence, we can test “cause and effect” hypotheses.
8. For example, if we repeatedly replace lowerdegreed nodes with higher-degreed nodes, we
conjecture that a random network evolves into a scale-free network. But conjectures may not be
true. In fact, the first illustration of open-loop emergence, below, shows this conjecture to be
wrong! The point is that we can test hypotheses and conjectures in a search for cause– effect

Consider the following open-loop emergent process. Initially, G(0) is a random network with n
nodes and m links. G(0) may be created by the ER generative procedure or the anchored random
network procedure described earlier .At each time step, select a node and link at random and
ask the question, “Can we rewire the randomly selected link such that it connects to a higher
degreed node?” In this case, the randomly selected node is selected if its degree is higher than
that of the randomly selected link’s head node. The link is rewired to point to the higher-
degreed node or left as is.
This simple micro rule repeats forever. We conjecture that a scale-free network will emerge from
the random network because over a long period of time a hub with very high degree emerges.
After a sufficient length of time, does the degree sequence of G(0) transition from a Poisson
distribution to a power law? We test this hypothesis in the following analysis.6 The “hub
emergence” micro rule is very simple—rewire a randomly selected link whenever it increases
the degree of a high-degreed node. Network.jar repeats the following Java method for
implementing the hub emergence micro rule for as long as the user desires:
10. Is this process another application of the law of increasing returns? After thousands of timesteps, does a scale-free
network emerge? We can check our hypothesis by simply inspecting the degree sequence that emerges from
160,000 timesteps! Figure 7.2a shows the degree sequence distribution of G(0)—the random network—and Fig. 7.2b
shows the distribution after 160,000 iterations. If the convergent network G(160,000) had evolved into a scale-free
network, its degree sequence distribution would be a power law. Clearly, this is not the case. Figure 7.2b shows a
skewed Poisson distribution, instead. Its smallest degreed nodes have one link, its largest degreed node has 178
links, and the peak of the distribution is at 4 links! Contrast this with the random network: a maximum hub with 18
links, minimum hub with zero links, and a peak at 10 links.

13. Cluster Emergence
Hub emergence leads to non-scale-free networks with hub structure. Is it possible to construct a
non-small-world network with high cluster coefficient? The answer is “Yes,” as we show next.
Beginning once again with a random network, suppose that we use feedback-loop emergence as
shown in Fig. 7.1b to enhance the cluster coefficient of an emergent network.
After each time step we guarantee that the overall cluster coefficient of the network is no less
than it was in the prior time step. Over time this network will increase its clustering—at least in
theory. Cluster coefficient emergence works as follows. Select a random link and random node.
Rewire the link to point to the new (random) node, if the overall cluster coefficient remains the
same or is increased. If the cluster coefficient decreases as a result of rewiring, revert to the
topology of the previous time step. Repeat this micro rule indefinitely, or until stopped.

16. DESIGNER NETWORKS
“most of the time.” Given a degree sequence g, we can construct a network containing nodes
with sequence g, if such a topology is realizable.7 The desired network may not be realizable
without allowing duplicate links between node pairs, however. In some cases, we may have to
sacrifice precision for practicality (no duplicates) in order to come close.
In this section, we show that restricting the total number of node degrees to the constraint
Pg¼2m, where m is the number of links in G, and using the proper preferential attachment
algorithm, we can produce any realizable network from an arbitrary starting point. Rewiring links
according to degree sequence g following the constraints described below, degree sequence
emergence produces a customized or “designer network” with exactly the topology we want.
Weusemethod NW_doSetStates(total_value, mean_value)tostore the desired degree sequence
g in the nodes of the initial network G(0).
17. When stored in each node as its state or value, the elements of g are called residual degree or
residual values. The objective is to transform G(0) to G(t) such that the degree sequence of G(t) is
exactly g. The initial elements of g will be decremented during the evolution of the desired network,
so that the emerged network matches g. If all values are zero after evolution, the network has
converged to the desired degree sequence, g.
The first parameter of NW_doSetStates(total_value, mean_value) is typically set to 2m because each
link connects two stubs, and the second parameter is typically set to the desired network’s average
degree value, l ¼n/m. If total value is less than 2m, the method reports an error message, and
returns. If mean value is too large, the network will not converge because it cannot insert enough
links to realize degree sequence g.
The state s of each node is limited to a minimum value of one and a maximum value of twice the
average degree: 1 2 l . The minimum degree value ensures that the evolved network is connected.
The maximum degree of any node is n21 (n 2 2 plus minimum of 1 assigned to all nodes), because
duplicate links are not allowed, and each node is able to connect to at most (n 21) others.
18. If the total number of degrees is odd, then at least one degree will remain unused because links
consume degrees in pairs. This method assumes the total number of degrees assigned to all
nodes to be an even number. Therefore, parameter total_value must be an even number. The
following parameters guarantee satisfactory results:
Method NW_doSetStates() loads the initial network G(0) with g, in preparation for emergence.
In addition to constraints on total_value and mean_value, the method must guarantee an even
number of stubs, stubs less than the maximum possible (n 21), and handle extreme values of n
and m.
19. Degree Sequence Emergence
Degree sequence emergence attempts to transform an arbitrary network into a network with a
prescribed degree sequence. Given an arbitrary starting network G(0) and degree sequence
g¼fd1,d2,...,dng, where di¼degree of node i, g¼ fd1,d2,...,dng, wheredi¼degree of node i, evolve
network G(final), into a network with degree sequence g. The target degree sequence g is stored in
the networkasvalue(vj)¼dj,foreachnode vj inG(0).Weclaimthatthedegreesequence of G(t) converges
to g when Pg¼2m, and duplicate links are allowed. Degree sequence emergence does not converge to
g whenPg , 2m because there are too many links. Emergence either stops or finds many
approximations to g, when Pg . 2m. When G(final) is realizable, degree sequence emergence
produces a “designer” network as specified by input values g.
The objective of degree network emergence is to decrease the difference between the initial degree
sequence of G(0) and the specified degree sequence g stored in each node asthe node’s state or
value. This may be possible by rewiring linksthat connect to nodes with too many links, thereby
decreasing each node’s degree until it matches—or approximates—the value specified in g. We do
this by disconnecting one or both ends of a link and reconnecting the broken link to a randomly
selected node. Note that we specifically do not attempt to increase the degree of nodes by purposely
attaching links to nodes with a deficiency of links.
20. For example, suppose that G(0)¼fN(0),L(0),fg, n¼4,and g¼f2,2,1,3g.Notethat
Pg¼2þ2þ1þ3¼(2)(4)¼8¼2m. Figure 7.7a shows G(0) before emergence, and Fig. 7.7b shows
G(100) after 100 timesteps have elapsed. Initially, the degree sequence g¼f2,3,2,1g, but after
approximately 100 timesteps, the network topology is changed to the objective: g¼f2,2,1,3g.
Emergence has closed the gap between the initial and desired degree of G.
Degree Sequence Emergence (per Node Value)
1. Store g ¼f d1,d2,...,dngin the value field of nodesfn1,n2,...,nngof G(0), for example,
vi¼value(ni)¼di.
2. Repeat indefinitely a. Select a random link Land random node r from G.L.head points to the
head node of link L, and L.tail connects to the tail node of L.

22. Generating Networks with Given Degree
Sequence
The foregoing raises a question regarding the creation of networks with a specific topology. We
know how to generate a random network, a scale-free network, and a small-world network, but
is it possible to generate any network desired with a given degree sequence? Molloy and Reed
showed how to do this using an algorithm like the one described above (Molloy, 1995). The
Molloy–Reed algorithm embodies the right idea, but has one major weakness—it does not
guarantee the desired topology every time.
The MR algorithm creates di stubs (half-links that lack the other endpoints) at each node, vi,
with assigned value di. Then, it performs a kind of preferential attachment selection process to
connect the loose end of each stub to another loose end at another node. Because links must
connect pairs of nodes, we assume Pg to be an even number. The process of connecting stubs
repeats until all stubs are connected or we run out of available nodes.
23. MR is implemented in Network.jar as method NW_doMolloyReed(). First, the method creates n nodes and stores
elements of g in each node’s value field. The total of all node values, Pg, must be an even number. Then it attempts
to connect Pg stubs together by random selection of nodes with yet-to-be-linked stubs.
Initially, the value stored at each node is equal to the initial residual degree specified by g. Each time the algorithm
m converts a pair of stubs into a link, the residual degree is decremented. If all residual degree values reach zero,
the desired network emerges. However, there is no guarantee that all node values will be decremented to zero. In
fact, it is likely that one or more stubs will fail to match with another stub. This requires that the preferential
attachment loop give up after numerous unsuccessful attempts. This limit on the method prevents infinite looping
when the emergent behavior does not converge.
