摘要:

A global optimality criterion for a family of non-convex optimization problems is proved using a result of J. Dedieu [2] concerning the closedness of the image of a closed set by a multivalued function.

摘要:

For a given multivalued mappingF:X→Yand a functiong:X×X→Rthis paper considers continuity properties of the (multivalued) mappingS(v) : ={[xbar]∈F-1(v)|g([xbar],x) 0 for allx∈F-1(v)}.

摘要:

A good deal of the global theory of optimization can be formulated without the concepts of function and linear space. Even the transitivity of the preference-relation is not necessary. In this paper we show, that also the proofs can be done without these concepts and under very weak additional assumptions.

摘要:

In this paper sufficient conditions for the connectedness of certain efficient point sets of convex optimization problems with multiple or random objectives are provided. Known concepts of efficiency like functional efficiency and proper efficiency (with respect to vector optimization problems) as well as efficiency with probability 1 (with respect to stochastic optimization problems with fixed feasible domain) are treated. By this the number of objectives that have to be minimized on the feasible domain (a subset of a Banach-space) can be infinite also.

摘要:

Relations between efficient solutions to discrete multicriteria decision problems and optimal solutions to corresponding parametric single-criterion problems are analyzed. In particular we consider such decision problems where one criterion is a sum function while the remaining criteria are bottleneck functions. In this case the multi-criteria problem can be reduced to a linear parametric sum problem. Depending upon the nature of its feasible set, the sum problem may belong to a class of computationally tractable optimization problems, By solving it parametrically we can then generate the set of all efficient solutions to the original multicriteria problem.
