One deterministic module has affine ranking function array_size + -1 * i and consists of 3 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[p][p] and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[p][p] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.2s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 6.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 2. Automata minimization 22.2ms AutomataMinimizationTime, 3 MinimizatonAttempts, 3 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 14 states and ocurred in iteration 3. Nontrivial modules had stage [2, 0, 1, 0, 0].
