Variability parity games are a recently proposed extension to well-known parity games that allow for verification of software product lines (SPLs). We propose new algorithms for solving variability parity games based on the existing priority promotion and SCC decomposition, and provide new heuristics for VPGs. We implemented these proposed algorithms, as well as an algorithm …continue reading

Ant Colony Optimization is an optimization algorithm that is inspired by the foraging behavior of ants. In this thesis I have applied Ant Colony Optimization to problems that are generated from the model checking problem, to Boolean equation systems and to parity games. The results of this research are mixed but we have discovered approaches …continue reading
