CrossoverPermutationBucket

java.lang.Object
- org.opt4j.operator.crossover.CrossoverPermutationBucket

All Implemented Interfaces:

Operator<PermutationGenotype<?>>, Crossover<PermutationGenotype<?>>, CrossoverPermutation
```
public class CrossoverPermutationBucket
extends Object
implements CrossoverPermutation
```
Crossover for the PermutationGenotype.

The bucket operator randomly runs through to permutation from the beginning to the end, and fill the current element into the new permutation if not existent.

Given two permutations

1 2 3 4 5 6 7 8 and 8 7 6 5 4 3 2 1

this results, for instance, in

1 8 2 7 3 6 4 5 or 8 7 1 2 3 6 5 4.
