The International Timetabling Competition 2007 has a follow up: the Nurse Rostering Competition 2010.
So expect a Drools Planner nurse rostering example soon :)
Building on the success of the two timetabling competitions, this competition on the nurse rostering problem aims to further develop interest in the general area of rostering and timetabling while providing researchers with models of the problems faced which incorporate an increased number of real world constraints.
The competition is composed of three tracks, called after the Olympic disciplines sprint, middle distance running and long distance running. These tracks represent distinct problem settings in practice and algorithm performance is often tuned to the available running time. The organisers do welcome researchers to trial their techniques on more than one track. The winner of each track receives a prize of €535 and free registration to PATAT in Belfast 2010.
Who's up for some competition? Bring it on!
