Chemical graphs, as other ones, are <i>regular</i> if all their vertices have the same degree. Otherwise, they are <i>irregular</i> and it is of interest to...

A new class of algorithms for solving nonlinearly constrained mixed variable optimization problems is presented. This class combines and extends the Audet-De...

This paper formulates and analyzes a pattern search method for general constrained optimization based on filter methods for step acceptance. Roughly, a f...

Cet article propose un modèle d’optimisation des stratégies de maintenance pour une meilleure intégration dans un plan de production préétabli. Le modèle est...

We present an exact algorithm and three applications of nonconvex quadratically constrained quadratic programming. First, we consider the pooling problem fro...

La majorité des auteurs traitant du problème de design d'implantation d'usine considèrent que la sélection de la configuration du réseau de manutention est f...

Generalized logical analysis aims at modelling complex biological systems, especially the so-called regulatory systems like genetic networks. The main feat...

The pooling problem, which is fundamental to the petroleum industry, describes a situation where products possessing different attribute qualities are mixed...

A common question asked by users of direct search algorithms is how to use derivative information at iterates where it is available. This paper addresses th...

This paper describes a method for evaluating the kinetic constants in a rate expression for catalytic combustion applications using experimental light-off c...

This paper contains a new convergence analysis for the Lewis and Torczon GPS class of pattern search methods for linearly constrained optimization. The ana...

This paper presents a multi-commodity network design approach to solve the problem of simultaneously locating I/O stations and determining the orientation o...

In the literature, thermal insulation systems with a fixed number of heat intercepts have been optimized with respect to intercept locations and temperature...

The recent Variable Neighborhood Search (VNS) metaheuristic combines local search with systematic changes of neighborhood in the descent and escape from loc...

Let <i>G</i> be a simple graph and <i>C</i> and <i>D</i> two proper colourings of <i>G</i>. The problem of colour switching consists of finding a sequence ...

We study empirically the topology of the local minima of the 3-SAT problem. In particular, we analyze the size of the plateaus, their altitude, their attrac...

In the last 15 years, considerable efforts have been placed on integrating product and process design. This integration can improve product quality, reduce...

An FMS environment requires a flexible and adaptable material handling system. Automated guided vehicles (AGV) provide such a system. One of the component...

If it is assumed that the final product of bromination of C₆₀ will obey two rules, (i) that no two <i>sp</i>³ carbons may be adjacent,...

This paper describes a decision support system based on a sophisticated mixed integer linear programming model, EUGENE, developed to help the regional decis...
