... 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 WORK? Although genetic algorithms are simple to describe and program, their behavior can be complicated, and many open questions exist about how they work and for...
