WebThe order crossover (OX) was proposed by Davis [ 26 ]. It builds offspring by choosing a subtour of a parent and preserving the relative order of bits of the other parent. Consider, for example, the two parents tours are as follows (with randomly two cut points marked by “ ”): The offspring are produced in the following way.
