This document discusses knowledge-based logical agents and concepts from propositional logic. It introduces how knowledge bases represent what agents know and can be used to determine actions. Propositional logic syntax and semantics are explained using sentences about pits and breezes in the Wumpus world. Key concepts in logic are defined such as logical equivalence, validity, satisfiability and the relationship between inference, entailment and sound/complete derivation of sentences.
This document introduces algorithms that are polynomial time versus non-polynomial time and defines NP-complete problems. It discusses that NP-complete problems include Satisfiability (SAT), Traveling Salesman, Knapsack and Clique problems. These problems are difficult to solve in polynomial time and are mapped to each other through polynomial time reductions. While we can solve them in exponential time, finding a polynomial time algorithm would mean P=NP.
Discrete math is the branch of mathematics that does not rely on limits. It is well-suited to describe computer science concepts precisely as computers operate discretely in discrete steps.

This document defines sets and set operations. A set is an unordered collection of elements. Sets can be represented visually using Venn diagrams. Set operations like union, intersection, difference describe how sets relate to each other. Functions map elements from one set to another. Functions can be one-to-one, onto, or bijective. Mathematical induction is a method to prove statements for all positive integers, by proving the base case and inductive step. Exercises demonstrate using sets, functions, and induction to solve problems.
This document summarizes key concepts from Chapter 2 of the textbook "Discrete Mathematics and Its Applications". It introduces fundamental mathematical structures including sets, functions, sequences, and summations. Some key points covered include: the definition of sets and set operations like union and intersection; defining functions as mappings between sets and discussing one-to-one, onto, and bijective functions; introducing sequences and their common patterns like arithmetic and geometric progressions; and defining summations and exploring properties of geometric series. Examples and figures are provided to illustrate these essential discrete structures and their relationships.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Propositional Logic is the logic of compound
statements built from simpler statements
using so-called Boolean connectives.
Some applications in computer science:
• Design of digital electronic circuits.
• Expressing conditions in programs.
• Queries to databases & search engines.

4. Definition of a Proposition
Definition: A proposition (denoted p, q, r, …) is simply:
• a statement (i.e., a declarative sentence)
– with some definite meaning, (not vague or ambiguous)
• having a truth value that’s either true (T) or false (F)
– it is never both, neither, or somewhere “in between!”
• However, you might not know the actual truth value,
• and, the value might depend on the situation or context.
• Later, we will study probability theory, in which we assign degrees
of certainty (“between” T and F) to propositions.
– But for now: think True/False only!

5. Examples of Propositions
• “It is raining.” (In a given situation.)
• “Beijing is the capital of China.” • “1 + 2 = 3”
But, the following are NOT propositions:
• “Who’s there?” (interrogative, question)
• “La la la la la.” (meaningless interjection)
• “Just do it!” (imperative, command)
• “Yeah, I sorta dunno, whatever...” (vague)
• “1 + 2” (expression with a non-true/false value)
Topic #1 – Propositional Logic
6. An operator or connective combines one or
more operand expressions into a larger
expression. (E.g., “+” in numeric exprs.)
• Unary operators take 1 operand (e.g., −3);
binary operators take 2 operands (eg 3 4).
• Propositional or Boolean operators operate
on propositions (or their truth values)
instead of on numbers.

8. The Negation Operator
The unary negation operator “¬” (NOT)
transforms a prop. into its logical negation.
E.g. If p = “I have brown hair.”
then ¬p = “I do not have brown hair.”

9. The Conjunction Operator
The binary conjunction operator “” (AND)
combines two propositions to form their
logical conjunction.
E.g. If p=“I will have salad for lunch.” and
q=“I will have steak for dinner.”, then
pq=“I will have salad for lunch and
I will have steak for dinner.”
Remember: “” points up like an “A”, and it means “ND”

conjunction
p1 p2 … pn
of n propositions
will have 2n rows
in its truth table.
• Also: ¬ and operations together are suffi-
cient to express any Boolean truth table!

11. The Disjunction Operator
The binary disjunction operator “” (OR)
combines two propositions to form their
logical disjunction.
p=“My car has a bad engine.”
q=“My car has a bad carburetor.”
pq=“Either my car has a bad engine, or
my car has a bad carburetor.” After the downward-
pointing “axe” of “”
splits the wood, you
can take 1 piece OR the
other, or both.
Topic #1.0 – Propositional Logic: Operators
Meaning is like “and/or” in English.
12. • Note that pq means
that p is true, or q is
true, or both are true!
• So, this operation is
also called inclusive or,
because it includes the
possibility that both p and q are true.
• “¬” and “” together are also universal.

13. Nested Propositional Expressions
• Use parentheses to group sub-expressions:
“I just saw my old friend, and either he’s
grown or I’ve shrunk.” = f (g s)
– (f g) s would mean something different
– f g s would be ambiguous
• By convention, “¬” takes precedence over
both “” and “”.
– ¬s f means (¬s) f , not ¬ (s f)

14. A Simple Exercise
Let p=“It rained last night”,
q=“The sprinklers came on last night,”
r=“The lawn was wet this morning.”
Translate each of the following into English:
¬p =
r ¬p =
¬ r p q =
“It didn’t rain last night.”
“The lawn was wet this morning, and
it didn’t rain last night.”
“Either the lawn wasn’t wet this
morning, or it rained last night, or
the sprinklers came on last night.”
Topic #1.0 – Propositional Logic: Operators
15. The Exclusive Or Operator
The binary exclusive-or operator “” (XOR)
combines two propositions to form their
logical “exclusive or” (exjunction?).
p = “I will earn an A in this course,”
q = “I will drop this course,”
p q = “I will either earn an A in this course,
or I will drop it (but not both!)”
Topic #1.0 – Propositional Logic: Operators
16. • Note that pq means
that p is true, or q is
true, but not both!
• This operation is
called exclusive or,
because it excludes the
possibility that both p and q are true.
• “¬” and “” together are not universal.

17. Note that English “or” can be ambiguous
regarding the “both” case!
“Pat is a singer or
Pat is a writer.” -
“Pat is a man or
Pat is a woman.” -
Need context to disambiguate the meaning!
For this class, assume “or” means inclusive.

18. The Implication Operator
The implication p q states that p implies q.
I.e., If p is true, then q is true; but if p is not
true, then q could be either true or false.
E.g., let p = “You study hard.”
q = “You will get a good grade.”
p q = “If you study hard, then you will get
a good grade.” (else, it could go either way)

19. Examples of Implications
• “If this lecture ends, then the sun will rise
tomorrow.” True or False?
• “If Tuesday is a day of the week, then I am
a penguin.” True or False?
• “If 1+1=6, then Bush is president.”
True or False?
• “If the moon is made of green cheese, then I
am richer than Bill Gates.” True or False?
Topic #1.0 – Propositional Logic: Operators
20. Why does this seem wrong?
• Consider a sentence like,
– “If I wear a red shirt tomorrow, then Osama bin Laden
will be captured!”
• In logic, we consider the sentence True so long as
either I don’t wear a red shirt, or Osama is caught.
• But, in normal English conversation, if I were to
make this claim, you would think that I was lying.
– Why this discrepancy between logic & language?
21. Resolving the Discrepancy
• In English, a sentence “if p then q” usually really
implicitly means something like,
– “In all possible situations, if p then q.”
• That is, “For p to be true and q false is impossible.”
• Or, “I guarantee that no matter what, if p, then q.”
• This can be expressed in predicate logic as:
– “For all situations s, if p is true in situation s, then q is also
true in situation s”
– Formally, we could write: s, P(s) → Q(s)
• That sentence is logically False in our example,
because for me to wear a red shirt and for Osama to
stay free is a possible (even if not actual) situation.
– Natural language and logic then agree with each other.
22. English Phrases Meaning p q
• “p implies q”
• “if p, then q”
• “if p, q”
• “when p, q”
• “whenever p, q”
• “q if p”
• “q when p”
• “q whenever p”
• “p only if q”
• “p is sufficient for q”
• “q is necessary for p”
• “q follows from p”
• “q is implied by p”
We will see some equivalent
logic expressions later.

23. Converse, Inverse, Contrapositive
Some terminology, for an implication p q:
• Its converse is: q p.
• Its inverse is: ¬p ¬q.
• Its contrapositive: ¬q ¬ p.
• One of these three has the same meaning
(same truth table) as p q. Can you figure
out which?

25. The biconditional operator
The biconditional p q states that p is true if and
only if (IFF) q is true.
p = “Bush wins the 2004 election.”
q = “Bush will be president for all of 2005.”
p q = “If, and only if, Bush wins the 2004
election, Bush will be president for all of 2005.”

26. Biconditional Truth Table
• p q means that p and q
have the same truth value.
• Note this truth table is the
exact opposite of ’s!
Thus, p q means ¬(p q)
• p q does not imply
that p and q are true, or cause each other.

29. Bit Strings
• A Bit string of length n is an ordered series
or sequence of n0 bits.
– More on sequences in §3.2.
• By convention, bit strings are written left to
right: e.g. the first bit of “1001101010” is 1.
• When a bit string represents a base-2
number, by convention the first bit is the
most significant bit. Ex. 11012=8+4+1=13.

30. Counting in Binary
• Did you know that you can count
to 1,023 just using two hands?
– How? Count in binary!
• Each finger (up/down) represents 1 bit.
• To increment: Flip the rightmost (low-order) bit.
– If it changes 1→0, then also flip the next bit to the left,
• If that bit changes 1→0, then flip the next one, etc.
• 0000000000, 0000000001, 0000000010, …
…, 1111111101, 1111111110, 1111111111
