Permutation chromosome is based on short array chromosome, but has two features:
/// <summary> /// Crossover operator. /// </summary> /// /// <param name="pair">Pair chromosome to crossover with.</param> /// /// <remarks><para>The method performs crossover between two chromosomes – interchanging /// some parts between these chromosomes.</para></remarks> /// public override void Crossover(IChromosome pair) { PermutationChromosome p = (PermutationChromosome)pair; // check for correct pair if ((p != null) && (p.length == length)) { ushort[] child1 = new ushort[length]; ushort[] child2 = new ushort[length]; // create two children CreateChildUsingCrossover(this.val, p.val, child1); CreateChildUsingCrossover(p.val, this.val, child2); // replace parents with children this.val = child1; p.val = child2; } }
/// <summary> /// Initializes a new instance of the <see cref="PermutationChromosome"/> class. /// </summary> /// /// <param name="source">Source chromosome to copy.</param> /// /// <remarks><para>This is a copy constructor, which creates the exact copy /// of specified chromosome.</para></remarks> /// protected PermutationChromosome(PermutationChromosome source) : base(source) { }
