One nondeterministic module has 2-nested ranking function (if -1 * \old(c) + 8 > 0 then 1 else 0), (if -1 * \old(c) + 8 > 0 then -1 * \old(c) + 8 else -1 * \old(c) + \old(b)) and consists of 14 locations. One nondeterministic module has affine ranking function -1 * \result + -1 * c + 9 and consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.1s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 14.8s. Construction of modules took 0.2s. Büchi inclusion checks took 1.9s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
