API Specification

org.moeaframework.core.operator.subset
Class SSX

java.lang.Object
  extended by org.moeaframework.core.operator.subset.SSX
All Implemented Interfaces:
Variation

public class SSX
extends Object
implements Variation

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.


Constructor Summary
SSX(double probability)
          Constructs a SSX operator.
 
Method Summary
 Solution[] evolve(Solution[] parents)
          Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions.
static void evolve(Subset s1, Subset s2)
          Evolves the specified variables using the SSX operator.
 int getArity()
          Returns the number of solutions that must be supplied to the evolve method.

Constructor Detail

SSX

public SSX(double probability)
Constructs a SSX operator.

Parameters:
probability - the probability of applying this operator
Method Detail

evolve

public static void evolve(Subset s1,
                          Subset s2)
Evolves the specified variables using the SSX operator.

Parameters:
s1 - the first subset
s2 - the second subset

evolve

public Solution[] evolve(Solution[] parents)
Description copied from interface: Variation
Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions. By contract, the parents must not be modified. The copy constructor should be used to create copies of the parents with these copies subsequently modified.

Specified by:
evolve in interface Variation
Parameters:
parents - the array of parent solutions
Returns:
an array of child solutions

getArity

public int getArity()
Description copied from interface: Variation
Returns the number of solutions that must be supplied to the evolve method.

Specified by:
getArity in interface Variation
Returns:
the number of solutions that must be supplied to the evolve method
