One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 4 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 32.6s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 6.5s. Construction of modules took 22.5s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
