One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[x_ref][x_ref] + 1 and consists of 4 locations. One deterministic module has affine ranking function 2147483647 + -2 * unknown-#memory_int-unknown[y_ref][y_ref] and consists of 4 locations. One nondeterministic module has affine ranking function 2147483647 + -2 * unknown-#memory_int-unknown[y_ref][y_ref] and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 24 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 32.0s and 8 iterations. TraceHistogramMax:3. Analysis of lassos took 28.8s. Construction of modules took 0.4s. Büchi inclusion checks took 2.5s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 26 StatesRemovedByMinimization, 5 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 [2, 0, 1, 0, 0].
