Dear colleagues,

 

The Algorithms Lab of the University of Mons (Department of Computer =

Science, Faculty of Science) is very pleased to invite you to a seminar =

given by Jay Yellen (Rollins College, Florida) on Friday May 22. Jay =

Yellen is well known as the co-author of the book =C2=AB Graph Theory =

and its applications =C2=BB (with J. Gross). This event is free and =

everybody is welcome but, as sandwiches and drinks will be provided, =

please send us an email before May 21 (hadrien.melot [at] umons.ac.be =

) if you intend to come.

 

 

 

A dual-objective course-timetabling problem: minimize conflict and =

create compact schedules

Friday 22 May, 12:15

Salle du Conseil, Grands Amphith=C3=A9=C3=A2tres

Plaine de Nimy, UMONS

 

 

 <>Abstract. The talk will focus on describing a metaheuristic approach =

to coloring the vertices of a weighted graph whose edges have =

2-component weights reflecting the two objectives. The vertex- and =

color-selection strategies and a priority queue for partial colorings =

use linear combinations of various heuristics that are based on the =

underlying structure of the graph as the coloring proceeds.  A =

mixed-integer formulation that gives an exact solution will also be =

presented, and comparisons between the two approaches will be given. The =

talk will conclude with the introduction of the robust-chromatic-number =

problem, a pure graph theory problem that arises naturally from the task =

of modifying a timetable.

 

 

Please forward this announcement to potentially interested colleagues.

 

We hope to see you soon in Mons !

 

Pierre Hauweele and Hadrien M=C3=A9lot
