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 5 locations. The remainder module has 6993 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.5s and 34 iterations. TraceHistogramMax:7. Analysis of lassos took 10.1s.
