An efficient algorithm has been proposed and its implementation in a multicore environment has been done and tested. This paper has two goals. First one is to tune the developed algorithm to increase the speedup of the multi\-threaded variant. The second one is to extend the algorithm to compute not only the Pareto\-front \(in the criteria space\), but also the Pareto\-set \(in the decision space\). Numerical results for suitable test problems are presented."]
