Codd's Self-Replicating Computer
Edgar Codd's 1968 design for a self-replicating cellular automaton has never been implemented. Partly this is due to its enormous size, but we have also identified four problems with the original specification that would prevent it from working. These problems potentially cast doubt on Codd's central assertion, that the eight-state space he presents supports the existence of machines that can a...
متن کاملThe evolution of self-replicating computer organisms
A computer model is described that explores some of the possible behavior of biological life during the early stages of evolution. The simulation starts with a primordial soup composed of randomly generated sequences of computer operations selected from a basis set of 16 opcodes. With a probability of about 10 -4, these sequences spontaneously generate large and inefficient self-replicating "or...
متن کاملStudying Evolution with Self-Replicating Computer Programs
A critical discussion is presented on the use of self-replicating program systems as tools for the formulation of generalised theories of evolution. Results generated by such systems must be treated with caution, but, if used properly, they can ooer us unprecedented opportunities for empirical , comparative studies. A new system called Cosmos is introduced, which is based upon Ray's Tierra 15]....
متن کاملMinimal self-replicating systems.
Minimal self-replicating systems typically consist of three components: a product molecule, and two substrate molecules that become joined to form another product molecule. An important characteristic of self-replicating systems is the ability of the product to catalyze the formation of additional product, resulting in autocatalytic behavior. Recent advances in the area of self-replication have...
متن کاملSimulating Self-replicating Machines
A simulation framework is described in which sliding tiles moving in a discrete two-dimensional grid can be put together to build machines. The tiles can perform logical and mechanical functions, and can be connected to each other. A self-replicating machine has been designed in this environment and its operation is summarised. Observations are made about the usefulness and the limitations of t...
