One deterministic module has affine ranking function N + -1 * i and consists of 4 locations. One deterministic module has affine ranking function M + -1 * j and consists of 4 locations. One deterministic module has affine ranking function -1 * k + N and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.7s and 4 iterations. TraceHistogramMax:0. Analysis of lassos took 1.8s. Construction of modules took 0.1s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 0. 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].
