Theory of self-reproducing automata von Neumann J.
Publisher: UMl Reprint University Illinois 1966 Ed

The second principle) account for two processes: a) homogenous replication (assembly of identical DNA molecules); and b) heterogeneous reproduction (self-generation of similar, though morphologically distinct entities). For example, a gene that improves proof-reading . The basic theory that underpins most types of PC virus was outlined in John von Nueman's scienfic paper published back in 1966. €�The Theory of Self-Reproducing Automata”. He argued that self-reproducing systems require a universal constructor, defined as an algorithm for a Turing machine that can construct any system (e.g., within a 2-dimensional cellular automata) based on its linear description. Noteworthy are also the so-called Pengi implementations [Agre and Chapman 1987] [4] – based on activity theory – and situated automata, with an epistemological substratum (Rosenschein and Kaelbling [1987]) [4, 41]. It is similar to what John von Neumann [4] called a “universal constructor ” and which, together with a controller, a duplicator and a symbolic description of the machine, are the necessary component of a self-replicating automaton. €�Life” here means a single self-reproducing and self-sustaining biological cell. According to Gregory Chaitin “the world is a giant computer”, “a scientific theory is a computer program that calculates the observations” [3]. The work of John von Neumann on the “Theory of self-reproducing automata” is published. First, the theory of a hypercycle considers a genome as a community of mutually beneficial (i.e., cross-catalytic) self-replicating elements [9]. "Theory of Self-Reproducing Automata" that I bought as an undergrad in 1968. The Creeper virus, an experimental self-replicating program, is written by Bob Thomas at BBN Technologies.
