Member Data Documentation

size_t samchon::library::GAParameters::generation

protected

A number of generation of evolution.

Definition at line 29 of file GAParameters.hpp.

Referenced by GAParameters(), and getGeneration().

size_t samchon::library::GAParameters::population

protected

A number of population in a generation.

Definition at line 34 of file GAParameters.hpp.

Referenced by GAParameters(), and getPopulation().

size_t samchon::library::GAParameters::tournament

protected

A number of tournament in a selection.

Definition at line 39 of file GAParameters.hpp.

Referenced by GAParameters(), and getTournament().

double samchon::library::GAParameters::mutationRate

protected

Rate of mutate ocurrence.

A mutation rate determines the percentage of occurence of mutation in a sequence list.

• Value from 0.0 to 1.0

Note

• When mutationRate is too high, it is hard to ancitipate studying on genetic algorithm.
• When mutationRate is too low and initial set of genes(GeneArray) is far away from optimal, the evolution tends to wandering outside of he optimal.
