One nondeterministic module has affine ranking function unknown-#memory_int-unknown[d][d] and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.5s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 14.4s. Construction of modules took 0.1s. Büchi inclusion checks took 2.8s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 6. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 39 StatesRemovedByMinimization, 4 NontrivialMinimizations. 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 [4, 0, 2, 0, 0].
