In this work a new approach to parent selection based on Grid-value in multiobjective genetic algorithm is proposed. Here grid is used as a frame to determine the location of individuals in the objective space. Every solution inside the grid maintains an objective-rank vector and summation value. Summation value is the scalar fitness and used to discriminate individuals instead of Pareto-dominance relation. Since multiple solutions occupy same grid have same Summation-value, an adaptive selection mechanism is used in order to avoid duplicate selection and thereby enhancing spread of solution on the Pareto front. The multi-objective genetic algorithm based on the proposed selection scheme is tested on problems of CEC09 competition. The algorithm has shown either comparable or good performance on few unconstrained test problems.
