Saddlepoint Theory for Nondifferentiable Multiobjective Fractional Programming
Chanchal Singh, Morgan A Hanson · Journal of Information and Optimization Sciences · 1986
Saddlepoint theory is developed for the nondifferentiable multiobjective fractional programming problem. Necessary and sufficient conditions of Fritz John and Kuhn-Tucker type are established. As expected, only necessary conditions require convexity restrictions. All functions are assumed to be nondifferentiable.
