One deterministic module has affine ranking function x and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.4s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1. 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 [1, 0, 0, 0, 0].
