One deterministic module has affine ranking function x and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.8s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 2.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
