One deterministic module has affine ranking function -2 * i2 + 19 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.2s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.8s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 4.
