One deterministic module has affine ranking function -1 * \old(y) + unknown-#memory_int-unknown[x_ref][x_ref] and consists of 6 locations. One deterministic module has affine ranking function -1 * aux-__VERIFIER_nondet_int()-aux + unknown-#memory_int-unknown[y_ref][y_ref] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] + -1 * unknown-#memory_int-unknown[z_ref][z_ref] and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 21 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 394.3s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 12.6s. Construction of modules took 12.3s. Büchi inclusion checks took 369.2s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 12 StatesRemovedByMinimization, 2 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 [3, 0, 0, 0, 0].
