genetic algorithm

Genetic algorithms are a family of computational search and learning methods inspired by biological evolution.  Evolution takes place on a population of individuals, each of which represents a candidate solution to a given problem.  At a given generation, each individual's fitness is calculated according to a user-defined fitness function.  A selection process probabilistically chooses the fittest individuals to reproduce (with variation resulting from crossover and mutation); their offspring make up the next generation.   The algorithm runs for either a fixed number of generations, or until an individual is found whose fitness is above a user-defined threshold.
