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. 3 modules have a trivial ranking function, the largest among these consists of 10 locations. The remainder module has 41570 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.5s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 10.1s.
