Problem 638. Uniform binary crossover

Created by Vitor Yano

Given two binary vectors, return the two children by combining the genes of them using a binary crossover mask.

More information: Uniform crossover

  • Parents and mask are row vectors of the same size N;
  • Output is a 2 x N matrix containing both children;
  • The first child must have genes from the first parent at the positions where the mask is true, and genes from the second parent where the mask is false;
  • The second child must have genes from the first parent at the positions where the mask is false, and genes from the second parent where the mask is true;
  • The mask is also supplied.

Example:

mask    = [1 0 0 0 1 1 1 0 0];
parent1 = [0 0 0 1 1 1 0 0 0];
parent2 = [1 1 0 0 1 0 1 1 0];
children = [0 1 0 0 1 1 0 1 0;
            1 0 0 1 1 0 1 0 0];
