Abstract
The paper discusses the organization of the International Timetabling Competition (ITC 2019), which intends to motivate further research on complex university course timetabling problems coming from practice. Thanks to the UniTime timetabling system, we have collected a strong set of benchmark instances with diverse characteristics for the competition. The key novelty lies in the combination of student sectioning with standard time and room assignment of particular course events. The paper analyzes the real-world course timetabling problems present in the competition. The characteristics of thirty competition instances are described together with their representative features, which are discussed institution by institution. The existing solvers are described and compared based on their competition, current, and time-limited results whenever available. As of October 2023, the competition website has about 490 registered users from 66 countries worldwide and is kept up to date with new results.
期刊介绍：
The Journal of Scheduling provides a recognized global forum for the publication of all forms of scheduling research. First published in June 1998, Journal of Scheduling covers advances in scheduling research, such as the latest techniques, applications, theoretical issues and novel approaches to problems. The journal is of direct relevance to the areas of Computer Science, Discrete Mathematics, Operational Research, Engineering, Management, Artificial Intelligence, Construction, Distribution, Manufacturing, Transport, Aerospace and Retail and Service Industries. These disciplines face complex scheduling needs and all stand to gain from advances in scheduling technology and understanding.
