gaft.operators.crossover

Uniform Crossover operator implementation.

class gaft.operators.crossover.uniform_crossover.UniformCrossover(pc, pe=0.5)

Bases: gaft.plugin_interfaces.operators.crossover.Crossover

Crossover operator with uniform crossover algorithm, see https://en.wikipedia.org/wiki/Crossover_(genetic_algorithm)

Parameters:

• pc (float in (0.0, 1.0]) – The probability of crossover (usaully between 0.25 ~ 1.0)
• pe (float in range (0.0, 1.0]) – Gene exchange probability.

cross(father, mother)

Cross chromsomes of parent using uniform crossover method.

Parameters:population (gaft.components.Population) – Population where the selection operation occurs. Returns:Selected parents (a father and a mother) Return type:list of gaft.components.IndividualBase

gaft.operators.crossover.uniform_crossover.random() → x in the interval [0, 1).
