abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
we consider nonconvex vector optimization problems with variable ordering structures in banach spaces. under certain boundedness and continuity properties we present necessary conditions for approximate solutions of these problems. using a generic approach to subdifferentials we derive necessary conditions for approximate minimizers and approximately minimal solutions of vector optimizatio...
In this paper, some properties of pseudoinvex functions, defined by means of limiting subdifferential, are discussed. Furthermore, the Minty vector variational-like inequality, the Stampacchia vector variational-like inequality, and the weak formulations of these two inequalities defined by means of limiting subdifferential are studied. Moreover, some relationships between the vector vari...

این پایان نامه مشتمل بر سه فصل است که در فصل اول به معرفی مفاهیم مورد نیاز از جمله نگاشت های kkm (kenastere-kuratowski-mazurkiewicz) و نگاشت های kkm تعمیم یافته که ابزاری برای حل مسائل تعادل هستند پرداخته ایم . در فصل دوم قضایای نقطه ثابت را برای توابع مجموعه مقدار در فضاهای فاقد ساختار جبری ( g-convex ) با استفاده از قضایای فصل اول مورد مطالعه قرار داده ایم . و بالاخره در فصل سوم مسئله تعادل ب...
In this paper, we establish weak and strong duality theorems for a pair of multiobjective symmetric dual problems. This removes several omissions in the paper "Symmetric and self duality in vector optimization problem, Applied Mathematics and Computation 183 (2006) 1121-1126".
