Abstract
We consider the problem of satisfying the maximum number of constraints of an instance of the Periodic Event Scheduling Problem (Pesp). This is a key issue in periodic railway timetable construction, and has many other applications, e.g. for traffic light scheduling.
We generalize two (in-) approximability results, which are known for Maximum-K-Colorable-Subgraph. Moreover, we present a deterministic combinatorial polynomial time algorithm. Its output violates only very few constraints for five real-world instances.
Supported by the DFG Research Center “Mathematics for key technologies” (Matheon) in Berlin.
