A Chance-Constrained Model and Cutting Planes for Fixed Broadband Wireless Networksel is reformulated as an integer linear program and valid inequalities are derived for the corresponding polytope. Computational results show that by an exact separation approach the optimality gap is closed by 42% on average.

Formulations and Branch-and-Cut Algorithm for the ,-rooted Mini-Max Spanning Forest Problemrced through Generalized Subtour Breaking inequalities while the second uses Directed cutset constraints. We implement a Branch-and-cut method based on the first formulation that also computes combinatorial lower bounds from the literature and implements a Linear Programming based multi-start heuris

The Two Level Network Design Problem with Secondary Hop Constraintsusing either the primary or the .. Thereby, the secondary technology is cheaper but less reliable and hence, hop constraints on the length of each secondary path are imposed. In addition, in some applications facility opening costs need to be paid for ., i.e., for nodes where the change of technolog

A Polyhedral Approach for Solving Two Facility Network Design Problemmmunication demands are met by installing a mix of facilities of both capacities on the edges to minimize total cost. We consider 3-partitions of the original graph which results in smaller 3-node subproblems. The extreme points of this subproblem polyhedron are enumerated using a set of proposed th
