One deterministic module has affine ranking function i and consists of 3 locations. One nondeterministic module has affine ranking function i and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.6s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 3.1s.
