One nondeterministic module has affine ranking function ((-1 * y) + x) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.4s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 3.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
