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.
