Class Replace

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

public class Replace
extends Object
implements Variation

Replacement mutation operator. Randomly replaces one of the members in the subset with a non-member.

This operator is type-safe.


Constructor Summary
Replace(double probability)
          Constructs a replacement mutation operator with the specified probability of mutating a variable.
 
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 subset)
          Evolves the specified subset using the replacement mutation operator.
 int getArity()
          Returns the number of solutions that must be supplied to the evolve method.

Constructor Detail

Replace

public Replace(double probability)
Constructs a replacement mutation operator with the specified probability of mutating a variable.

Parameters:
probability - the probability of mutating a variable
Method Detail

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

evolve

public static void evolve(Subset subset)
Evolves the specified subset using the replacement mutation operator.

Parameters:
subset - the subset to be mutated

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
