One deterministic module has affine ranking function ((-1 * i) + length) and consists of 5 locations. One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 10 locations. One deterministic module has affine ranking function null and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 42.1s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 40.1s. Construction of modules took 0.2s. Büchi inclusion checks took 1.5s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
