One deterministic module has affine ranking function 21 * unknown-#length-unknown[in] + -2 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * idx_in + unknown-#length-unknown[in] + -1 * in and consists of 2 locations. 11 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.5s and 14 iterations. TraceHistogramMax:11. Analysis of lassos took 16.8s. Construction of modules took 0.2s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 13.
