One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function (length2 + ((long long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 22 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.2s and 7 iterations. TraceHistogramMax:2. Analysis of lassos took 8.1s. Construction of modules took 0.2s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 6.
