One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.0s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.7s. Construction of modules took 4.0s. Büchi inclusion checks took 3.2s. Highest rank in rank-based complementation 3. Minimization of det autom 4.
