	Christopher Langton - Wikipedia, the free encyclopedia
		Computer scientist Christopher Langton was one of the founders of the field of artificial life.
		He coined the term in the late 1980s when he held the first "International Conference on the Synthesis and Simulation of Living Systems" (otherwise known as Artificial Life I) at the Los Alamos National Laboratory in 1987.
		Langton created the Langton ant and Langton loop, both landmark simple artificial life simulations.

	NKS-SJSU: Self Reproducing Cellular Automata and Programs (Site not responding. Last check: 2007-11-03)
		Chris Langton, took it upon himself to create a creature that fulfilled Von Neumann's criteria of reproduction.
		Langton observed that the capability of computational universality found in the self-reproducing automata of von Neumann is not known to be present in any self-replicating molecules or in the biological structure of any known living entity.
		In Neumann’s and Langton’s automata also, there is a concept of instructions and data on the input tape which are replicated in the offspring.

		Chris spoke of the dream of ALife to build artificial biologies, so that the universal properties of all forms of life whether biological or artificial can be understood.
		Chris talked about his concept of "collectionism" or micro-macro dynamics, which is both top-down and bottom-up, where the macro behavior emerges in a bottom up way from the micro local rules of simple agents, yet the macro emergent effects feed back in a top-down way on the behavior of the agents.
		Chris Langton's three ALife conferences were characterised by a mix of creative fun and solid competence.

	The Third Culture - Chapter 21
		Chris is taking a physical way of thinking of things like phase transitions and dynamical systems and applying it to biological organisms.
		It was mathematical work, by Norman Packard and Langton himself, on so-called cellular automata that led to this conjecture, and further research on those automata may or may not support the idea, but there are now many other reasons to pursue the subject.
		Chris has managed in that way to attract a great deal of attention to the field of plectics and to draw a lot of people into it.

	Lotus Artificial Life - HAL and Langton's loops (Site not responding. Last check: 2007-11-03)
		HAL was vaguely inspired by the self-reproducing loops of Chris Langton.
		Langton's loops (1079) were themselves inspired by the "Cellular Automata" work of E. Codd (1968) which extended the work of John von Neumann as presented in his "Theory of Self-Reproducing Automata" (1966).
		Langton's loops were brittle and it was difficult to transmit heritable information from one loop to another by their 'arms' crossing one another - as any such interaction was likely to destroy both the cells involved.

	Genesis of Artificial Life by Terry Smith (Site not responding. Last check: 2007-11-03)
		According to Chris Langton who coined the term, "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....
		Christopher Langton would show that the "'molecular logic of the living state' can be captured by the interactions of virtual automata and thus that the existence of artificial life within cellular automata is a distinct possibility" (Langton 1986, 120).
		And as Chris Langton has said, "The most surprising lesson we have learned from simulating complex physical systems on computers is that complex behavior need not have complex roots" (Waldrop 279).

	Wall Street Journal Article
		Langton's simulator can take flight only by harnessing the processing power -- and possibly much of the information -- in every computer inside the enterprise it's modeling.
		Langton, of Santa Fe, N.M., thinks the product holds the solution to his challenge -- though he acknowledges that the new technology harbors potential risks as well.
		LANGTON moved full-time to the citadel of complexity studies, the Sante Fe Institute, in 1994.

	artifical intelligence, artificial life
		Artificial Life was christened in 1987 in New Mexico by Chris Langton, a researcher at Los Alamos National Laboratories and at the Santa Fe Institute for the Sciences of Complexity.
		Artificial Life, in its U.S. incarnation, takes as its charter the idea that life "is a property of the organization of matter, rather than a property of matter itself,"[2] maintaining, as a consequence, that life may be faithfully modeled -- or more ambitiously, created -- on computers.
		Chris Langton has proposed that Artificial Life is not just about life-as-we-know-it, but about life-as-it-could-be.

	ALife6: Preface
		Clearly, Chris Langton's work and the Artificial Life conferences that he spawned in 1987, have ushered in a new epoch of ALife research.
		Similarly, Chris Langton's model of self-replication as virtual state machines on a Cellular Automaton (Langton langton84, langton86) is a second classic reference in Alife.
		Sayama introduces in these pages a form of `death' into Langton's model, transforming the crystalline but abiotic structrues into much more life-like forms that even seem to evolve.

		This suggests that the "road" configuration is an attractor of Langton's ant.
		Langton's ant can also be described as a cellular automaton, where most of the grid is colored fl or white, and the "ant" square has one of eight different colors assigned to encode the combination of fl/white state and the current direction of motion of the ant.
		There is also a simple name giving scheme for such ants: for each of the successive colours, a letter 'L' or 'R' is used to indicate whether a left or right turn should be taken.

	Artificial Life
		I've always had an interest in how the mind works, how computers work, and how computers might be made to act more like the mind.
		After attending the first "Artificial Life" conference in 1987 (named and organized by Chris Langton, then at Los Alamos), I finally began to think I might actually have a clue as to how one might pursue that subject to its logical conclusion.
		The field of Artifical Life, or ALife, or Theoretical Biology (as Chris sometimes wishes he had named it) is about many things--not just a more bottom-up, practical approach to artificial intelligence, though that is the portion of the field that excites me the most.

		Omni: "So then, aren't you artificial life guys playing God?" Chris Langton: "Well, yeah, in a way I have to admit it."[1] The dream of creating life is hard to resist.
		For this I turn to a treatise on machines in ancient India written by a Sanskritist named V. Raghavan.[5] In Sanskrit a machine is called a yantra.
		As defined by the Samarangana Sutradhara of King Bhoja, in the twelfth century, a yantra is a device that "controls and directs, according to a plan, the motions of things that act each according to its own nature."[6] This is close to Langton's definition of life.

	The Reality Club: Darwin Among the Machines
		It's interesting that neither Chris Langton, who is credited with founding the field of artificial life, nor Tom Ray, who has been one of it most cited practitioners, knew about Barricelli's work until very recently, long after their own work had begun.
		Langton cites one of Barricelli's many papers in his bibliography, but I gather from Chris that this was an indirect cite; he has not really studied Barricelli's work, only vaguely knew it existed.
		First of all, I must acknowledge how much I owe to Chris Langton, Thomas Ray, and many others who left Barricelli's publications untouched, so that, without doing a single experiment of my own, I stumbled upon the makings of a whole chapter in my book.
