One deterministic module has affine ranking function -2 * blastFlag + 1 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 735 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.5s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 4.7s.
