One deterministic module has affine ranking function -1 * blastFlag + 1 and consists of 3 locations. One deterministic module has affine ranking function -2 * blastFlag + 7 and consists of 3 locations. One deterministic module has affine ranking function s__state and consists of 5 locations. 32 modules have a trivial ranking function, the largest among these consists of 6 locations. The remainder module has 22314 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 28.5s and 34 iterations. TraceHistogramMax:7. Analysis of lassos took 14.3s.
