org.moeaframework.core.operator.permutation
Class Insertion

java.lang.Object
  extended by org.moeaframework.core.operator.permutation.Insertion
All Implemented Interfaces:
Variation

public class Insertion
extends Object
implements Variation

Insertion mutation operator. Randomly selects an entry in the permutation and inserts it at some other position in the permutation.

This operator is type-safe.


Constructor Summary
Insertion(double probability)
          Constructs an insertion mutation operator with the specified probability of mutating a variable.
 
Method Summary
static void evolve(Permutation permutation)
          Evolves the specified permutation using the insertion mutation operator.
 Solution[] evolve(Solution[] parents)
          Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions.
 int getArity()
          Returns the number of solutions that must be supplied to the evolve method.

Constructor Detail

Insertion

public Insertion(double probability)
Constructs an insertion 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(Permutation permutation)
Evolves the specified permutation using the insertion mutation operator.

Parameters:
permutation - the permutation 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
