摘要: The comnionality hypothesis introduced in this paper sugrcsts that the prescrvation of cummnn schemata i ? centml source power n rccomhination operators. A commonalilyhared crossovcr operator proceeds two steps: I idcntify maximal coininon schema parents. and 2) coinplcte solution with a construction hcuristic. Using framework, new crossover opcrators are proposed for sequcncing problcms. first uses partial order basis cummonalily. This is shown lu perform well on Traveling Salesman Problem (TSP); it finds best-known soIution~ many Sequential Ordcring (SOP) instances. second based sub-tours/edgesl t used to demonstrate utility liamework designing hybrid genetic algorithms.
