One deterministic module has affine ranking function \old(n) and consists of 6 locations. 7 modules have a trivial ranking function, the largest among these consists of 28 locations. The remainder module has 59 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 494.8s and 10 iterations. TraceHistogramMax:5. Analysis of lassos took 207.6s. Construction of modules took 118.7s. Büchi inclusion checks took 168.0s. Highest rank in rank-based complementation 3. Minimization of det autom 0. Minimization of nondet autom 9.
