On a Variant of the Ellipsoid Method: Using Simplices instead of Ellipsoidsory and presents the numerical results of an implementation of the method. The results suggest that in practice the number of iterations used by it may be considerably less than that of the ellipsoid method.

A Heuristic Algorithm for Very-Large Scale Set Covering Problems1 if . ∈ 5, .. = 0 otherwise. For notational convenience, for each row . ∈ . let ..:= {. ∈ .: .. = 1} be the set of the columns covering row . Analogously, for each column . ∈ . let ..:= {. ∈ .: .. = 1} be the row subset covered by column . Moreover, let . denote the number of nonzero entries of .

The Euclidian Traveling Salesman Selection ProblemSSP) is introduced. The problem is restricted to the Euclidian case where the TSP can be formulated as follows: Given . cities in the plane and their Euclidian distances, the problem is to find the shortest TSP-tour, i.e. a closed path visiting each of the . cities exactly once.

The Simple Plant Location Problem with Spatial Interaction: Formulation and Solution Methodsng the transportation costs. In order to better model such situations, . has been introduced in location models. Simple plant location problems with spatial interaction between the travelers have been treated in [2, 3, 5, 14, 15, 16, 17], modelled as a nonlinear, mixed integer programming problem.

Continuous-Time Dynamic Reward Structuresve off-diagonal elements. We show that several results for the standard Markov case also carry over to this more general case, most notably: uniformization, error bound analysis and comparison results.
