For reference and for citations, please use: https://ieeexplore.ieee.org/document/996017

Parameters:

  • mutator – Mutator to use.

  • population_size – Population size, which will be used as both batch size for proposing new individuals and tourament size for finding the elites among recently added populations.

  • seed – Random seed for initializing the population. If None, the system time will be used.

Returns:

An Evolution object.
