One deterministic module has affine ranking function a8 and consists of 4 locations. One deterministic module has affine ranking function a17 and consists of 4 locations. One deterministic module has affine ranking function a7 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 10 locations. The remainder module has 17182 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 38.3s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 29.5s.
