“…Many authors have discussed optimality conditions and duality results for nonlinear programming problems containing the square root of a positive semidefinite quadratic function, for example those discussed by Mond [31] and Zang and Mond [38]. Mishra et al [25] proved necessary and sufficient optimality conditions for nondifferential semi-infinite programming problems involving square root of quadratic functions, see, for more details [6,32,33,35]. Furthermore, the term with the square root of a positive semidefinite quadratic function has been replaced by a more general function, namely, the support function of a compact convex set, whose the subdifferential can be simply expressed.…”
