Order based crossover

WebFor these scenarios you usually go for the classic PMX (Partially Mapped Crossover) and Interchange Mutation. But, there are plenty of other crossover algorithms you can use OX1, OX2 (both variants of the Order Based Crossover), Shuffle Crossover, Ring Crossover, etc. Let's start from the mutation, that is easier. WebDec 25, 2014 · 3.1 Order crossover 1 This variant of the order-based crossover was proposed in [ 14 ]. The main feature of this operator is that it considers the order of the genes important, not their positions. It obtains the offspring by choosing a subtour of one parent and preserving the relative order of genes from the other parent.
