Computers in Graph Theory
A survey is made of computer systems which help to obtain and sometimes provide automatically proofs, conjectures and refutations in graph theory.

This paper investigates a new variation in the continuous single facility location problem. Specifically, we address the problem of locating a new facility...
BibTeX referenceOn Uniform k-Partition Problems
We study various uniform <i>k</i>-partition problems which consist in partitioning <i>m</i> sets, each of cardinality <i>k</i>, into <i>k</i> sets of cardin...
BibTeX referenceA General Multi-Shift Scheduling System
Rotating work schedules are encountered in several industries and public sector organizations where work is carried out 24 hours a day, seven days a week. ...
BibTeX reference
We survey computers systems which help to obtain and sometimes provide automatically conjectures and refutations in algebraic graph theory.
BibTeX referenceAnalysis of Generalized Pattern Searches
This paper contains a new convergence analysis for the Lewis and Torczon GPS class of pattern search methods for linearly constrained optimization. The ana...
BibTeX referencePanchromatic Chains and Paths
A generalization of the Roy-Gallai theorem on the chromatic number of a graph is derived which is also an extension of several other results of Berge and of...
BibTeX referenceIntegral Complete Split Graphs
We give characterizations of integral graphs in the family of complete split graphs and a few related families of graphs.
BibTeX reference
Variable neighborhood search (VNS) is a recent metaheuristic for solving combinatorial and global optimization problems whose basic idea is systematic chang...
BibTeX referenceAmbulance Location and Relocation Models
This article traces the evolution of ambulance location and relocation models proposed over the past thirty years. The models are classified in two main ca...
BibTeX reference
This paper introduces a new kind of operational crew scheduling problem which consists in simultaneously modifying, as necessary, the existing flight depart...
BibTeX reference
This paper deals with dispatching systems in open-pit mines. It illustrates the different strategies that exist for solving the dispatching problem and ana...
BibTeX reference
This paper presents a multi-commodity network design approach to solve the problem of simultaneously locating I/O stations and determining the orientation o...
BibTeX reference
Although airlines plan aircraft routes and crew schedules in advance, perturbations occur everyday. As a result, flight schedules may become infeasible and ...
