An eta-approximation approach to duality in mathematical programming problems involving r-invex functions

摘要

An eta-approximation approach introduced by Antczak [T. Antczak, A new method of solving nonlinear mathematical programming problems involving r-invex functions, J. Math. Anal. Appl. 311 (2005) 313-323] is used to obtain a Solution Mond-Weir dual problems involving r-invex functions. eta-Approxiniated Mond-Weir dual problems are introduced for the eta-approximated optimization problem constructed in this method associated with the original nonlinear mathematical programming problem. By the help of eta-approximated dual problems various duality results are established for the original mathematical programming problem and its original Mond-Weir duals.
