One deterministic module has affine ranking function \old(n) and consists of 4 locations. One deterministic module has affine ranking function -1 * n and consists of 5 locations. One deterministic module has affine ranking function n and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.6s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 13.5s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
