Compact MILP Formulations for the ,-Center Problem,ted center is minimized. For this problem we propose two new and compact integer formulations..Our first formulation is an improvement of a previous formulation. It significantly decreases the number of constraints while preserving the optimal value of the linear relaxation. Our second formulation c

Polytope Membership in High Dimension, halfspaces. Standard data-structures and brute force methods cannot scale, due to the curse of dimensionality. We design an efficient algorithm, by reduction to the approximate Nearest Neighbor (ANN) problem based on the construction of a Voronoi diagram with the polytope being one bounded cell. We

The Stop Number Minimization Problem: Complexity and Polyhedral Analysis,ts request for a ride from an origin point to a destination point, and a fleet of capacitated vehicles must satisfy all requests. The goal is to minimize the number of pick-up/drop-off operations. In [.], a special case was conjectured to be NP-Hard. In this paper we give a positive answer to this c

Maximum Concurrent Flow with Incomplete Data,ncomplete data. We call this new problem the Incomplete Maximum Concurrent Flow Problem (IMCFP). The main objective of IMCFP is to complete the missing information assuming the known and unknown data form a MCFP and one of its optimal solutions. We propose a new solution technique to solve the IMCFP

The Minimum Rooted-Cycle Cover Problem,s of rooted-cycles, which generalize classical vertex-covers, and packing of disjoint rooted cycles, where two rooted cycles are vertex-disjoint if their only common vertex is the root node. We use Menger’s theorem to provide a characterization of all rooted graphs such that the maximum number of ve
