Duality theorem for fractional functional programming in complex space
Duality theorems for a class of non-linear programming problems.
Duality of linear programming is used to establish an important duality theorem for a class of non-linear programming problems. Primal problem has quasimonotonic objective function and a convex polyhedron as its constraint set.
