One deterministic module has affine ranking function y and consists of 3 locations. One nondeterministic module has affine ranking function y and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. The remainder module has 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.0s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 5.6s.
