One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function y and consists of 3 locations. One deterministic module has affine ranking function x and consists of 3 locations. One nondeterministic module has affine ranking function y and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.0s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 1.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
