In.this article, a n.vel scalarization.techn.que, called the improved objective-con.train. approach, is in.roduced to fin. efficien. solution. of a given.multiobjective programmin. problem. The presen.ed scalarized problem exten.s the objective-con.train. problem. It is demon.trated that how addin. variables to the scalarized problem, can.lead to fin. con.ition. for (weakly, properly) Pareto optimal solution.. Applyin. the obtain.d n.cessary an. sufficien. con.ition., two algorithms for gen.ratin. the Pareto fron. approximation.of bi-objective an. three-objective programmin. problems are design.d. These algorithms are easy to implemen. an. can.achieve an.even.approximation.of (weakly, properly) Pareto optimal solution.. These algorithms can.be gen.ralized for optimization.problems with more than.three criterion.fun.tion., too. The effectiven.ss an. capability of the algorithms are demon.trated in.test problems.
