RT Journal Article SR 00 ID 10.1007/BF00941179 A1 Valyi, I. T1 Approximate saddle-point theorems in vector optimization JF Journal of Optimization Theory and Applications YR 1987 FD 1987-12 VO 55 IS 3 SP 435 OP 448 K1 Convex optimization problems, approximate nondominated solutions, saddle points, primal-dual pairs of solutions AB The paper contains definitions of different types of nondominated approximate solutions to vector optimization problems and gives some of their elementary properties. Then, saddle-point theorems corresponding to these solutions are presented with an application relative to approximate primal-dual pairs of solutions.
