Generalized fractional programming problems containing locally subdifferentiable andρ-Univex functions
Shashi Kant Mishra · Optimization · 1997
Parametric and nonparametric sufficient optimality conditions are established for a class of nonsmooth generalized fractional programming problems containing ρ-univex functions. Subsequently, these optimality criteria are utilized as a basis for construction of two parametric and four parameter–free duality models and proving appropriate duality theorems
