Detailed Description

template<typename GeneType = double>
class galib::benchmark::DeJongF5Function< GeneType >

Implementation of De Jong's Function F5 (Shekel's Foxholes).

A highly multi-modal 2D function with 25 local minima (foxholes). Global minimum: f(-32, -32) ≈ 0.998.

Template Parameters

GeneType

The numeric type of the genes.
