One deterministic module has affine ranking function -5 * aux-#t~loopctr7-aux + 3 * unknown-#length-unknown[d] and consists of 5 locations. One deterministic module has affine ranking function -1 * aux-#t~loopctr9-aux + unknown-size-unknown and consists of 2 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.4s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 6.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 15.5ms AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 8 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
