In this paper we deal with the problem of building a timetable for the courses of a university faculty. We propose an integer linear programming approach based on column generation...
Abstract. Constraint programming based column generation is a hybrid optimization framework recently proposed that uses constraint programming (CP) to solve column generation subpr...
Column generation is a state-of-the-art method for optimally solving di cult large-scale optimization problems such as airline crew assignment. We show how to apply column generati...
