This paper formulates the problem of maximal closure on a graph with resource constraints as an integer programming problem with binary variables, and propo...

La méthode de génération de colonnes est couramment utilisée pour résoudre des problèmes d'optimisation de grande taille. En pratique, on observe fréquemmen...

We study both the continuous and discrete problems of maximizing the product of two linear functions subject to all variables being between 0 and~1. We fir...

Cet article présente une étude comparative des algorithmes de flot maximum pour la résolution du problème de fermeture maximale sur un graphe. Plusieurs ap...

It is shown that the anytime deduction procedure for probabilistic entailment of Frisch and Haddawy does not have the correctness property when the probabil...

Clustering with a criterion which minimizes the sum of squared distances to cluster centroids is usually done in a heuristic way. An exact polynomial algori...

We study the problem of finding a shortest collision-free path for a point car-like robot maneuvering around polygonal obstacles in a room bounded by a poly...

The paper is concerned with sustainable cooperation in a vertical two-member channel of distribution over an infinite planning horizon. Sustainable intertem...

We study the problem of minimizing the peak load in single-command cycle shared storage policies. The peak load is the maximum of the daily material handlin...

Diverses classes de modèles permettant la génération de solutions pour des problèmes d'implantations d'usines sont décrits. La description de chacune des c...

We consider a model for communications network design that includes the optimal location of switches (of which there are several types) and the design of th...

Two new path problems in graphs are studied: MINRANGE, i.e., find a path from a vertex <i>s</i> to a vertex <i>t</i> with the smallest possible range of a...

In this paper a new approach for the facility layout problem is presented. This approach combines genetic algorithms with linear programming to design the ...

We consider the problem of minimizing, over a fixed horizon, the peak load in single-command cycle dedicated storage policies. The daily load is the expecte...

The multi-depot vehicle scheduling problem with time windows consists of scheduling a fleet of vehicles to cover a set of tasks at minimum cost. Each task i...

A review is made of models and algorithms for probabilistic satisfiability and its extensions. The basic probabilistic satisfiability problem, in decision f...

Extension of input-output functions for generating units allows simultaneous solution of the static unit commitment and economic dispatch problems by dynami...

Let <i>G =</i> (<i>V,E</i>) be an undirected graph and <i>c</i> any vector in Z₊^{<i>V</i>(<i>G</i>)}. Denote by <img src="chi.gif" alig...

In the Generalized Traveling Salesman Problem (GTSP), the aim is to determine a least cost Hamiltonian circuit or cycle through several clusters of vertic...

The problem of assigning locomotives to train-segments is very important for railway companies, in view of the high cost of operating locomotives. The prob...
