| Abstract: | Niched Pareto genetic algorithm (NPGA) is a superior method to solve the multi-objective optimization problems because it is applicable to a large range of variable problems,and can search nonlinear and discontinuous space without need for continuity and second-order partial differential operators. However,it is inefficient in finding the Pareto optimal solutions due to two shortcomings:premature convergence to local area and low convergence speed. In this paper,an improved NPGA (INPGA) is developed to prom... |
