One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] + -1 * z and consists of 6 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[z_ref][z_ref] + unknown-#memory_int-unknown[y_ref][y_ref] and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.2s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 9.5s. Construction of modules took 0.1s. Büchi inclusion checks took 2.3s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 6 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 17 states and ocurred in iteration 3. Nontrivial modules had stage [2, 0, 0, 0, 0].
