A column generation approach to train timetabling on a corridor
We propose heuristic and exact algorithms for the (periodic and non-periodic) train timetabling problem on a corridor that are based on the solution of the LP relaxation of an ILP...

Path Planning for Groups Using Column Generation
In computer games, one or more groups of units need to move from one location to another as quickly as possible. If there is only one group, then it can be solved efficiently as a ...

Second-Best Combinatorial Auctions - The Case of the Pricing-Per-Column Mechanism
One of the main contributions of classical mechanism design is the derivation of the Groves mechanisms. The class of Groves mechanisms are the only mechanisms that are strategy-pr...

Linear Programming Boosting by Column and Row Generation
Abstract. We propose a new boosting algorithm based on a linear programming formulation. Our algorithm can take advantage of the sparsity of the solution of the underlying optimiza...
