Odd Minimum Cut-Sets and b-Matchings

MW Padberg, MR Rao - Mathematics of Operations …, 1982 - pubsonline.informs.org
We show that the determination of a minimum cut-set of odd cardinality in a graph with even
and odd vertices can be dealt with by a minor modification of the polynomially bounded …

Simple criteria for optimal portfolio selection

EJ Elton, MJ Gruber, MW Padberg - The Journal of finance, 1976 - JSTOR
There have been two approaches in the literature to solving the first of these problems. One
has been to use a single index model to generate variancecovariance structures. The …

Solving large-scale symmetric travelling salesman problems to optimality

H Crowder, MW Padberg - Management Science, 1980 - pubsonline.informs.org
We report the solution to optimality of ten large-scale symmetric travelling salesman problems.
The travelling salesman problem (TSP) is one of the standard problems of the Operations …
