Evolutionary algorithms forms a family of algorithms inspired by the theory of evolution, that solve various problems. - They evolve a set of solutions to a given problem, in order to produce the best results. - These are stochastic algorithms, because they iteratively use random processes. - The vast majority of these methods are used to solve optimization problems, and may be also called "metaheuristics". - They are also ranked among computational intelligence methods, a domain close to artificial intelligence. -

Component-based framework

+

Component-based framework

-

Designing an algorithm with EO consists in choosing what components you want to use for your specific needs, just as building a structure with Lego blocks.

-

If you have a classical problem for which available code exists (for example if you have a black-box problem with real-valued variables), you will just choose components to form an algorithm and connect it to your fitness function (which computes the quality of a given solution).

-

If your problem is a bit more exotic, you will have to code a class that represents how your individuals (a solution to your problem) are represented, and perhaps some variations operators, but most of the other operators (selection, replacement, stopping criteria, command-line interface, etc.) are already available in EO.
