Max. memory is 16.1GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 8 terminating modules (4 trivial, 4 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op6 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.3s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 3.3s. Construction of modules took 0.0s. Büchi inclusion checks took 1.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 6. Automata minimization 0.2s AutomataMinimizationTime, 6 MinimizatonAttempts, 5492 StatesRemovedByMinimization, 6 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 2409 states and ocurred in iteration 3. Nontrivial modules had stage [4, 0, 0, 0, 0].
