A Life Artificial Life Overview Created for Models of Learning and Instruction taught by Dr. Cafolla Group Members: David Manset and Jaclyn Clark
What Is A Life? 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.” Spectrum of Artificial Life
Definition “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 Artificial Life has initiated unprecedented alterations to society and science with aspects of living organisms that cannot be categorized as quite human.
Developers seek to… create real, carbon-based living organisms and behaviors such as: Growth Adaptation Reproduction or Self replication Socialization Learning Death But artificial life still seeks to: survive without the input complicated proteins, or other large molecules, or life sustaining elements evolve and adapt over time through a natural selection process
Wet: Biochemistry This area is an attempt to stimulate origin of life with self-replicating and self-producing efforts. In Vitro method is when and experiment is given in a controlled environment outside of a living organism Example Chemical Substrates: molecules to which an enzyme acts
Second Life-One Example of Artificial Life 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/)
Early Contributors of Artificial Life John McCarthy coined Artificial Intelligence "the science and engineering of making intelligent machines.” Craig Reynolds In 1987 created familiar flocking behavior in groups of computer-designed "boids" like birds Used these rules for behvaior separation: steer correctly to prevent crowding alignment: steer in direction of other flockmates cohesion: steer to move toward the approximate position of local flockmates Provided a forerunner to computer animation 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.
Contributors Alan M. Turing Artificial Intelligence Pioneer Wrote “The Chemical Basis of Morphogenesis” in 1951 Machine intelligence: technology could be installed with intelligence the same way routine tasks were programmed
More Contributors John Von Neumann Termed “automaton" as any machine which behaved logically by joining environmental information with the machine’s own programming Claimed machines would self-replicating Machines would be logical and not necessarily requiring physical bodies
Practical Uses Social Networking Provides links to connect people with similar interests Interacting with gamers at the same skill level Education Allow study of living creatures vs. technology created life Use of computer for analytical thinking Many games replicate the movement pattern of organism groups in an interactive way for students Simulators provide first hand experience over description of a process Art 3 dimensional life like and enhanced images Fantasy and highly detailed images created and saved in computer storage (RAM)
