One deterministic module has affine ranking function NULL and consists of 6 locations. One deterministic module has affine ranking function NULL and consists of 5 locations. One deterministic module has affine ranking function NULL and consists of 9 locations. 2 modules have a trivial ranking function, the largest among these consists of 27 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 36.7s and 6 iterations.
