a non-empty open convex subset of R" and f: S~+ R", g: S—> R'", and h: S—> R'are
differentiable functions at xeX, an efficient solution or a candidate for an efficient solution.
Notations. Throughout this paper we use the following notations. The index set K={1, 2,..., k},
L={1, 2,..., I}, and M:{l, 2,..., m}. For xeX, the index set I={ieM: g,(x)=()} and J={ieM: g,»(x)< 0}=
