Genex v1.0.1-beta Genex.Evolution behaviour View Source

Evolution behaviour definition for Evolutionary algorithms.

Evolutions begin with init after the population has been created. The purpose of init is to define metrics, initiate a genealogy tree, and create a hall of fame. init is like the "constructor" of the evolution.

Callbacks

evaluation(population, opts)

Evaluates population according to fitness_fn.

init(population, opts)

Initialization of the evolution.
