Abstract
A new approach to a solution of a nonlinear constrained mathematical programming problem and its Mond–Weir duals is introduced. An η-approximated problem associated with a primal nonlinear programming problem is presented that involves η-approximated functions constituting the primal problem. The equivalence between the original mathematical programming problem and its associated η-approximated optimization problem is established under invexity assumption. Furthermore, η-approximated dual problems in the sense of Mond–Weir are introduced for the obtained η-approximated optimization problem in this method. By the help of η-approximated dual problems some duality results are established for the original mathematical programming problem and its original duals.
