One deterministic module has affine ranking function -1 * i + N and consists of 5 locations. One deterministic module has affine ranking function -1 * i + N and consists of 4 locations. The remainder module has 1299935 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 269.6s and 4 iterations. TraceHistogramMax:0. Analysis of lassos took 3.3s. Construction of modules took 0.2s. Büchi inclusion checks took 6.2s. Highest rank in rank-based complementation 1. Minimization of det autom 0. Minimization of nondet autom 0.
