Hybrid Genetic Algorithm with Multiparents Crossover for Job Shop Scheduling Problems

Figure 8

EPPX crossover.

(a) Example of EPPX

(b) First step—vector number 1; the first gene in parent 1 is selected and the same job from the other parents is removed

(c) Second step—previous selected gene will be deleted, first gene (after deletion) in parent 1 is selected, and the job from the other parents are removed

(d) Repeat—the process will continue until at the end of the vector
