Reachability Games on Extended Vector Addition Systems with States
We consider two-player turn-based games with zero-reachability and zero-safety objectives generated by extended vector addition systems with states. Although the problem of decidin...

Flexible Aliasing with Protection
Unwanted effects of aliasing cause encapsulation problems in object oriented programming. Nevertheless, aliasing is part of common and efficient programming techniques for expres...

Verifying Properties of Infinite Sequences of Description Logic Actions
The verification problem for action logic programs with non-terminating behaviour is in general undecidable. In this paper, we consider a restricted setting in which the problem be...

Adding cardinality constraints to integer programs with applications to maximum satisfiability
Max-SAT-CC is the following optimization problem: Given a formula in CNF and a bound k, find an assignment with at most k variables being set to true that maximizes the number of ...

A Note on Approximating MAX-BISECTION on Regular Graphs
We design a 0:795 approximation algorithm for the Max-Bisection problem restricted to regular graphs. In the case of three regular graphs our results imply an approximation ratio ...
