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<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 />
