Abstract:

Necessary and sufficient optimality conditions are derived for a nondifferentiable fractional minimax programming problem: Minimizex∈Rn [supy∈Y {(f(x,y) + (xTBx)1/2)/(h(x,y) − (xTDx)1/2)}] subject to g(x) ⩽ 0. where Y is a compact subset of Rn; f(·,·) : Rn × Rm → R and h(·,·) : Rn × Rm → R are C1 on Rn × Rm; g(·) : Rn → Rr is C1 on Rn; B and D are n × n symmetric positive semidefinite matrices. For this class of problems, two duals are proposed and weak, strong and strict converse duality theorems are established for each dual problem.
