• Research in the area of educational timetabling has been extensive and has changed significantly over the past two decades. Timetabling and scheduling problems are amongst the most well-studied NP-hard optimisation problems due to their direct importance and relevance in real-world situations. In the early days of timetabling research, it was common for authors to present results for bespoke problem instances taken from a single institution. The introduction of standardised benchmarks for examination timetabling in 1996 (Carter et al. 1996) and for course timetabling a few years later (via the first International Timetabling Competition, ITC-20021) contributed towards creating a more cohesive research community, able to directly compare computational results obtained by different solution methods.
