One deterministic module has affine ranking function \old(n) and consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.8s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 2.9s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. 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 0 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
