One nondeterministic module has affine ranking function x and consists of 3 locations. One nondeterministic module has affine ranking function x and consists of 3 locations. One nondeterministic module has affine ranking function d and consists of 3 locations. One nondeterministic module has affine ranking function d and consists of 3 locations. One nondeterministic module has affine ranking function y and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.9s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 2.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
