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. WebOrder based crossover operator (OBX) was proposed by Syswerda [4] which is a slight variation of the PBX operator. The OBX’s working procedures are as follows: Step 1: randomly select a set of positions in P1; Step 2: copy P2’s jobs except these in selected positions in P1 to C by keeping their positions in P2. WebOrder-based crossover (OX2) is a crossover operator for permutation encoded chromosomes. It is an operator that forces the order of several randomly selected positions in one parent to the other parent (Syswerda, 1991). Usage ox2 (x1, x2, cxon, cxoxk, ...)
