Peak memory consumption was 253.6MB. Max. memory is 8.0GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + N and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.4s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.4s. Construction of modules took 0.0s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 0.5s AutomataMinimizationTime, 1 MinimizatonAttempts, 7801 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 1.5s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [1, 0, 0, 0, 0].
