                                      DoubleGenotype p2)

Description copied from interface: Crossover

Performs a crossover for two Genotype parents. The resulting pair of Genotype offspring is returned.

Specified by:

crossover in interface Crossover<DoubleGenotype>

Parameters:

p1 - The first parent genotype for the crossover

p2 - The second parents genotype for the crossover

Returns:

The resulting pair of offspring genotypes
