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...

A mixed graph <i>G_{<img src="theta.gif">}</i> contains both undirected edges and directed arcs. A <i>k</i>-coloring of <i>G<sub><img src="theta.g...

The <i>p</i>-maxisum dispersion problem consists of locating <i>p</i> facilities at vertices of a network in order to maximize the sum of the distances betw...

Splitting a tree is defined as removing all edges of a chain and disconnecting one from the other edges incident with that chain. Splitting a forest is simu...

Cluster Analysis is at the crossroad of many disciplines, and has numerous and diverse methods and applications. Mathematical Programming (together with gra...

Consider an assignment problem in which persons are qualified for some but usually not all of the jobs. Moreover, assume persons belong to given seniority c...

Global optimization methods aim at finding the global optimum of a nonlinear and nonconvex function subject to nonlinear and nonconvex constraints. The main...

An overview is given, with new results, of mathematical models and algorithms for probabilistic logic, probabilistic entailment and various extensions. Anal...

Cylindrical aromatic compounds - fullerenes and hydrocarbons - are about to become highly interesting objects of chemical research. A tubulene (tubular ben...

In a first attempt to explain the good behavior of local improvement heuristics (such as Tabu Search and Simulated Annealing) for the <i>k</i>-coloring prob...

We derive from Boolean methods a transformation which, when it can be applied, builds from a graph <i>G =</i> (<i>V,E</i>) a new graph <i>G'=</i> (<i>V',E'<...

For a weighted graph <i>G =</i> (<i>V,E</i>), the maximum weighted <i>k</i>-coloring problem is to color a set of vertices of maximum weight using <i>k</i> ...

We describe two new classes of graphs for which the stability number can be computed in polynomial time. The first approach is based on an iterative procedu...

The purpose of this paper is to describe a new tabu search heuristic for the vehicle routing problem with capacity and route length restrictions. The algori...

This paper describes a domain criterion for a multicriteria problem, given a single decision maker. It then outlines possibilities for aggregating individua...

We address in this paper the problem of finding an optimal strategy for dealing with bottleneck machines and bottleneck parts in the cell formation process ...

We describe a new class of graphs for which the stability number can be obtained in polynomial time. The algorithm is based on an iterative procedure which...

In this paper the authors describe a heuristic principle for the solution of an important class of problems. Using real-world examples, it is then shown how...

This paper considers the archeological seriation problem defined over incidence matrices. Two procedures adapted from interchange algorithms for the travell...
