Abstract

We propose a multi-neighbourhood simulated annealing algorithm for the ITC-2007 version of the capacitated examination timetabling problem. The proposed solver is based on a combination of existing as well as newly proposed neighbourhoods that better exploit the disconnected structure of the underlying conflict graph and that explicitly deal with the assignment of exams to rooms. We use a principled tuning procedure to determine the parameters of the algorithm and assess the contribution of the various neighbourhoods by means of an ablation analysis. The resulting algorithm is able to compete with existing state-of-the-art solvers and finds several new best solutions for a variety of well-known problem instances.

多邻域模拟退火法解决 ITC-2007 年容纳性考试时间安排问题

摘要我们提出了一种多邻域模拟退火算法，用于解决 ITC-2007 版的有容量考试时间安排问题。所提出的求解器基于现有邻域和新提出的邻域的组合，这些邻域更好地利用了底层冲突图的断开结构，并明确地处理了考场分配问题。我们采用有原则的调整程序来确定算法参数，并通过消融分析来评估各种邻域的贡献。由此产生的算法能够与现有的最先进求解器相媲美，并为各种众所周知的问题实例找到了多个新的最佳解决方案。
