fixed some wording.
A '''genetic algorithm''' is a [[stochastic]] numerical algorithm used to solve problems where [[analytic]] or step-wise computation is impossible or intractable. Genetic algorithms are a popular subset of [[Evolutionary algorithms]] which use common concepts in [[evolutionary biology]] and principles of the [[Theory of evolution]] such as: [[inheritance]], [[mutation]], [[selection]], and [[recombination]].

Solutions to a problem are randomly generated and then allowed to interact in a modeled environment. Various solutions can [[breed]] with each other producing new combinations, also at random intervals certain elements of the solution can randomly mutate. The fit of any given solution to the problem is measured and those that are a better fit are selected for. This can either happen by increasing the rate of offspring reproduction in better solutions or by killing off solutions that perform worse.

Various solutions can [[breed]] with each other producing new combinations, also at random intervals certain elements of the solution can randomly mutate. The fitness of any given solution to the problem is measured by a fitness function and those that are a better fit are selected for.

Genetic algorithms are used in a wide subset of disciplines including: [[biology]], [[engineering]], [[medicine]] and [[chemistry]].
