Holland ... parallelism than the latter, since an instance of the former contains more schemas than an instance of the latter (2 100 versus 2 30 ). (This schema−counting argument is relevant t...

... illustrate how one might use a GA both to evolve solutions to an interesting problem and to model evolution and coevolution in an idealized way. One can think of many additional possible experiments, ... algorithms to simple automatic−programming tasks were performed by Cramer (1 985 ) and by Fujiki and Dickinson (1 987 ), among others. The recent resurgence of interest in autom...
