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 5 terminating modules (2 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * x) + 99) and consists of 5 locations. One deterministic module has affine ranking function (((long long) 2 * y) + 1) and consists of 3 locations. One nondeterministic module has affine ranking function (((long long) 2 * y) + 1) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.1s and 4 iterations. TraceHistogramMax:4. Analysis of lassos took 2.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 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].
