Evolutionary multi-objective optimisation EMO algorithms are preferred for solving the multi-objective optimisation MOO problems due to their ability of producing multiple solutions in a single run. In this study, hybridisation of the traditional sequential simplex method is considered with the evolutionary multi-objective differential evolution MODE algorithm for solving MOO problems. The hybrid strategy of MODE ensured that both the speed and accuracy are attained in a single algorithm. Various strategies of MODE algorithm are tested on several benchmark MOO test problems [both constrained namely, SCH, FON, KUR, ZDT1, ZDT2, ZDT4, and ZDT3 and ZDT4 and unconstrained namely, CONSTR and TNK]. Two widely accepted performance metrics convergence and diversity from the point of view of MOO study are considered for evaluating the performance of strategies of MODE algorithm. Pareto fronts are obtained using newly developed strategies of MODE and are compared with the Pareto front obtained using other EMO strategy NSGA-II. It is found that all the developed strategies of MODE algorithm converge to the true Pareto front for most of the test problems. However, the strategies of MODE result in slightly lower value of diversity metric as compared to NSGA-II for most of the test problems considered in this study.
