One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.9s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 2.4s. Construction of modules took 7.7s. Büchi inclusion checks took 6.9s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
