In this article, a novel scalarization technique, called the improved objective-constraint approach, is introduced to f.nd ef.icient solutions of.a given multiobjective programming problem. The presented scalarized problem extends the objective-constraint problem. It is demonstrated that how adding variables to the scalarized problem, can lead to f.nd conditions f.r (weakly, properly) Pareto optimal solutions. Applying the obtained necessary and suf.icient conditions, two algorithms f.r generating the Pareto f.ont approximation of.bi-objective and three-objective programming problems are designed. These algorithms are easy to implement and can achieve an even approximation of.(weakly, properly) Pareto optimal solutions. These algorithms can be generalized f.r optimization problems with more than three criterion f.nctions, too. The ef.ectiveness and capability of.the algorithms are demonstrated in test problems.
