A Life Presentation

  1. 1. A Life <br />Artificial Life Overview<br />Created for Models of Learning and Instruction taught by Dr. Cafolla<br />Group Members: David Manset and Jaclyn Clark<br />
  2. 2. What Is A Life? <br />Artificial Life: “is a field of study and an associated art form which examine systems related to life, its processes, and its evolution through simulations using computer models, robotics, and biochemistry.”<br />Spectrum of Artificial Life<br />
  3. 3. Definition <br />“Artificial Life is the name given to a new discipline that studies ‘natural’ life by attempting to recreate biological phenomena from scratch within computers and other ‘artificial’ media. A life complements the traditional analytic approach of traditional biology with a synthetic approach in which, rather than studying biological phenomena by taking apart living organisms to see how they work, one attempts to put together systems that behave like living organisms.- Chris G. Langton<br />Artificial Life has initiated unprecedented alterations to society and science with aspects of living organisms that cannot be categorized as quite human. <br />
  4. 4. Developers seek to…<br />create real, carbon-based living organisms and behaviors such as: <br />Growth<br />Adaptation<br />Reproduction or Self replication<br />Socialization<br />Learning<br />Death<br />But artificial life still seeks to:<br />survive without the input complicated proteins, or other large molecules, or life sustaining elements<br />evolve and adapt over time through a natural selection process<br />
  5. 5. Three types <br />
  6. 6. Wet: Biochemistry<br />This area is an attempt to stimulate origin of life with self-replicating and self-producing efforts. <br />In Vitro method is when and experiment is given in a controlled environment outside of a living organism<br />Example <br />Chemical Substrates: molecules to which an enzyme acts <br />
  7. 7. Real Examples<br />
  8. 8. Second Life-One Example of Artificial Life<br />Second Life® is a 3-D virtual world created by its Residents. Since opening to the public in 2003, it has grown explosively and today is inhabited by millions of Residents from around the globe.” (from http://secondlife.com/whatis/)<br />
  9. 9. Early Contributors of Artificial Life<br />John McCarthy<br /> coined Artificial Intelligence <br />"the science and engineering of making intelligent machines.” <br />Craig Reynolds<br /> In 1987 created familiar flocking behavior in groups of computer-designed "boids" like birds<br />Used these rules for behvaior<br />separation: steer correctly to prevent crowding<br />alignment: steer in direction of other flockmates <br />cohesion: steer to move toward the approximate position of local flockmates <br />Provided a forerunner to computer animation <br />Many scientists, mathematicians, professors, researchers, and intellectuals contributed to development of artificial life forms before computers even existed. Adjacent are a few men and their significant contributions. <br />
  10. 10. Contributors<br /> Alan M. Turing<br />Artificial Intelligence Pioneer<br />Wrote “The Chemical Basis of Morphogenesis” in 1951 <br />Machine intelligence: technology could be installed with intelligence the same way routine tasks were programmed<br />
  11. 11. More Contributors <br />John Von Neumann<br />Termed “automaton" as any machine which behaved logically by joining environmental information with the machine’s own programming<br />Claimed machines would self-replicating<br />Machines would be logical and not necessarily requiring physical bodies<br />
  12. 12. Practical Uses<br />Social Networking<br />Provides links to connect people with similar interests<br />Interacting with gamers at the same skill level<br />Education<br />Allow study of living creatures vs. technology created life<br />Use of computer for analytical thinking <br />Many games replicate the movement pattern of organism groups in an interactive way for students<br />Simulators provide first hand experience over description of a process<br />Art<br />3 dimensional life like and enhanced images<br />Fantasy and highly detailed images created and saved in computer storage (RAM)<br />
