One deterministic module has affine ranking function -1 * i + hi and consists of 5 locations. One deterministic module has affine ranking function -1 * i + N and consists of 7 locations. The remainder module has 6496360 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 244.1s and 4 iterations. TraceHistogramMax:0. Analysis of lassos took 3.5s. Construction of modules took 0.1s. Büchi inclusion checks took 8.3s. Highest rank in rank-based complementation 1. Minimization of det autom 0. Minimization of nondet autom 0. Automata minimization No data available. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [3, 0, 0, 0, 0].
