The Tera-Gridiron: A Natural Turf for High-Throughput Computing (2008)

Jeff Linderoth, François Margot, Greg Thain

Abstract — Teragrid resources are often used when high-performance computing is required. We describe our experiences in using Teragrid resources in a high-throughput manner, generating a...

An Approximate Dynamic Programming Approach to Benchmark Practice-based Heuristics for Natural Gas Storage Valuation (2008)

Guoming Lai, François Margot, Nicola Secom

The valuation of the real option to store natural gas is a practically important problem that entails dynamic optimization of inventory trading decisions with capacity constraints in the face of...

Improving bounds on the football pool problem via symmetry reduction and high-throughput computing. Submitted (2007)

Jeff Linderoth, François Margot, Greg Thain

The Football Pool Problem, which gets its name from a lottery-type game where partici-pants predict the outcome of soccer matches, is to determine the smallest covering code of radius one of ternary...

Optimization for Simulation: LAD Accelerator (2007)

Miguel A. Lejeune, François Margot

The goal of this paper is to address the problem of evaluating the performance of a system running under unknown values for its stochastic parameters. A new approach called LAD for Simulation, based...

Testing Cut Generators for Mixed-Integer Linear Programming (2007)

François Margot

In this paper, a methodology for testing the accuracy and strength of cut generators for mixed-integer linear programming is presented. The procedure amounts to random diving towards a feasible...

A Feasibility Pump for Mixed Integer Nonlinear Programs (2006)

Pierre Bonami, Gérard Cornuéjols, Andrea Lodi, François Margot

Abstract We present an algorithm for finding a feasible solution to a convex mixed integer nonlinear program. This algorithm, called Feasibility Pump, alternates between solving nonlinear programs...

Small Covering Designs by Branch-and-Cut (2000)

François Margot

A Branch-and-Cut algorithm for nding covering designs is presented. Its originality resides in the use of isomorphism pruning of the enumeration tree. A proof that no 4 (10; 5; 1)-covering design...

The Packing Property (1997)

Gérard Cornuéjols, G Erard, François Margot, Cornu Ejols, Bertrand Guenin, ...

. A clutter (V; E) packs if the smallest number of vertices needed to intersect all the edges (i.e. a transversal) is equal to the maximum number of pairwise disjoint edges (i.e. a matching). This...

Weak K-Majorization and Polyhedra (1996)

Geir Dahl, Geir Dahl, François Margot, Francois Margot

For integers k and n with k # n a vector x # R n is said to be weakly k-majorized by a vector q # R k if the sum of the r largest components of x does not exceed the sum of the r largest components...

Weak K-Majorization and Polyhedra (1995)

Geir Dahl, François Margot

For integers k and n with k # n avector x 2 R n is said to be weakly k-majorized byavector q 2 R k if the sum of the r largest components of x does not exceed the sum of the r largest components of...
