This paper presents a new approach to handle constrained optimization using evolutionary algorithms. The new technique converts constrained optimization to a two-objective optimization: one is the original objective function, the other is the degree function violating the constraints. By using Paretodominance in the multi-objective optimization, individual's Pareto strength is defined. Based on Pareto strength and Minimal Generation Gap (MGG) model, a new realrcoded genetic algorithm is

The results show that the new approach outperforms those existing techniques in feasibility, effectiveness and generality. Especially for some complicated optimization problems with inequality and equality constraints, the proposed method provides better numerical accuracy. . .
