Fuzzy sets theory may be used to solve multiple-attribute decision problems under uncertainty. Snmmm'y-A method is proposed to deal with multiple-alternative decision problems under uncertainty. It is assumed that all the alternatives in the choice set can be characterized by a number of aspects, and that information is available to assign weights to these(More)
This report contains a study on the weighted independent set problem. In particular , it deals with solving this problem by parallel branch-and-bound algorithms, in which the evaluation of the nodes is based on positive semideenite programming relaxation. There have been evaluated two diierent positive semideenite programs. Both programs provide an upper(More)
