Local crossover#

local_crossover() draws a random weight for each variable and sets the two offspring to the two weighted averages of the parents. Only DESDEO (LocalCrossover) provides this operator.

KS test results#

	moocore	desdeo
moocore		0.496
desdeo	0.496

Both implementations produce the same distribution of offspring.

Performance over number of parents#

DESDEO takes 39 to 70 times as long as moocore.

Performance over number of variables#

DESDEO takes 28 to 71 times as long as moocore.
