This work arises from the research of the Metaheuristics Network on the University Course Timetabling Problem. In a first phase straightforward implementations of different metaheuristics were compared on a common local search framework [4]. In a second phase problem specific knoweldge was exploited and several alternatives for local search and metaheuristics were considered. Many possibilities...

The Resource-Constrained Project Scheduling Problem (RCPSP) is concerned with single-item or small batch production where limited resources have to be allocated to dependent activities over time. Over the past few decades, a lot of work has been made with the use of optimal solution procedures for this basic problem type and its extensions. Brucker and Knust[1] discuss, how timetabling problems...

The High School Timetabling Problem requires the assignment of times and resources to events, while sets of required and desirable constraints must be considered. The most common approach for this problem is to employ metaheuristic methods. This work presents a matheuristic approach that combines a Variable Neighbourhood Search algorithm with mathematical programming-based neighbourhoods for hi...

The timetabling problem consists in fixing a sequence of meetings between teachers and students in a prefixed period of time (typically a week), satisfying a set of constraints of various types. [1] Course timetabling is a multidimensional NP-Complete problem. [2] In this paper we present MultiResource Timetabling Problem (MRTP), which is our model for generalized high-school timetabling proble...

Following the success of the First International Timetabling Competition in 2002, the timetabling research community is organising a new competition on this problem (opening August 1st). This new competition will be on three different timetabling problems, and one of the tracks concerns the course timetabling formulation that applies to Italian universities (called Curriculum-based Course Timet...

This paper presents our work on analysing high level heuristics within a graph based hyper-heuristic framework. Local search based methods (Tabu Search and steepest descent method) are compared as the high level heuristics within the graph based hyper-heuristic framework and the analysis of their neighborhood structures and performance on the high level landscape is carried out. An iterated ste...

Many researchers studying examination timetabling problems focus on either benchmark problems or problems from practice encountered in their institutions. Hyperheuristics are proposed as generic optimisation methods which explore the search space of heuristics rather than direct solutions. In the present study, the performance of tournament-based hyperheuristics for the exam timetabling problem...

The general timetabling problem is an assignment of activ ities to xed time intervals adhering to a prede ned set of resource availabilities Timetabling problems are di cult to solve and can be ex tremely time consuming without some computer assistance In this paper the application of constraint based reasoning to timetable generation is examined Speci cally we consider how a timetabling proble...
