Hello i want to use GA and BPSO in one .m file as one code and tell it as GA-BPSO Hybrid code ,please suggest me what changes i make in both so i can say it as hybrid and this Hybrid code have better performance than GA and BPSO individually?kindly write in code form may be i change mutation or crossover or velocity or position what ever may be suggested so these both become hybrid and gave improved performance.
