A Darwin machine (a 1987 coinage by William H. Calvin, by analogy to a Turing machine) is a machine that, like a Turing machine, involves an iteration process that yields a high-quality result, but, whereas a Turing machine uses logic, the Darwin machine uses rounds of variation, selection, and inheritance. In its original connotation, a Darwin machine is any process that bootstraps quality by utilizing all of the six essential features of a Darwinian process: A ''pattern'' is ''copied'' with ''variations'', where populations of one variant pattern ''compete'' with another population, their relative success biased by a ''multifaceted environment'' (natural selection) so that winners predominate in producing the further variants of the next generation (Darwin's ''inheritance principle''). More loosely, a Darwin machine is a process that utilizes some subset of the Darwinian essentials, typically natural selection to create a non-reproducing pattern, as in neural Darwinism. Many aspects of neural development utilize overgrowth followed by pruning to a pattern, but the resulting pattern does not itself create further copies. ''Darwin machine'' has been used multiple times to name computer programs after Charles Darwin. ==See also== * Artificial life * Artificial intelligence *"Darwin among the Machines" * Evolutionary computation * Evolutionary algorithm * Genetic algorithm * Universal Darwinism 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Darwin machine」の詳細全文を読む スポンサード リンク
