Application of Diploid Genetic Algorithm in Job-Shop Scheduling Problem

For the low efficiency and premature convergence of Sample Genetic Algorithm (SGA) application in job-shop scheduling problem (JSP) ,an improved algorithm, diploid genetic algorithm(DGA) is presented to resolve JSP. Comparing with SGA,DGA,the DGA improves searching efficiency and has strong ability to avoid premature convergence. The strategies and basic steps of solving JSP by DGA are summarized and generalized, and the program is compiled. The result of DGA in JSP proves its efficiency and feasibility.
