edu.cnu.mdi.sim.ga.triimage.UniformBlendCrossover

All Implemented Interfaces:

CrossoverOperator<PolygonChromosome>

public final class UniformBlendCrossover
extends Object
implements CrossoverOperator<PolygonChromosome>

Uniform crossover that treats each encoded triangle as an indivisible building block. All ten genes for a child triangle come from the same parent, preserving useful combinations of geometry, color, and opacity. Two complementary children are returned: whenever the first receives a triangle from one parent, the second receives the corresponding triangle from the other. This retains more population diversity than discarding half of each mating's genetic material.
