Abstract

In this paper, a Modified micro Genetic Algorithm MmGA is proposed for undertaking Multi-objective Optimization Problems MOPs. An NSGA-II inspired elitism strategy and a population initialization strategy are embedded into the traditional micro Genetic Algorithm mGA to form the proposed MmGA. The main aim of the MmGA is to improve its convergence rate towards the pareto optimal solutions. To evaluate the effectiveness of the MmGA, two experiments using the Kursawe test function in MOPs are conducted, and the results are compared with those from other approaches using a multi-objective evolutionary algorithm indicator, i.e. the Generational Distance GD. The outcomes positively demonstrate that the MmGA is able to provide useful solutions with improved GD measures for tackling MOPs.
