One deterministic module has affine ranking function null and consists of 3 locations. 6 modules have a trivial ranking function, the largest among these consists of 20 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.6s and 10 iterations. TraceHistogramMax:5. Analysis of lassos took 14.7s. Construction of modules took 0.2s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 9.
