One deterministic module has affine ranking function 15 + -2 * i2 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 60.5s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 59.9s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
