org.moeaframework.core.operator.subset.SSX

All Implemented Interfaces:

Configurable, Variation

public class SSX
extends TypeSafeCrossover<Subset>

Subset crossover. Similar to HUX for binary strings, SSX swaps half of the non-shared members of the two\ subsets.

This variation operator is type-safe.

SSX

public SSX(double probability)

Constructs a SSX operator.

Parameters:

probability - the probability of applying this operator
