Free memory was 133.1MB in the beginning and 132.1MB in the end (delta: 1.1MB). Peak memory consumption was 2.1MB. 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 6 terminating modules (2 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (y + ((long) -1 * x)) and consists of 4 locations. One deterministic module has affine ranking function (y + ((long) -1 * x)) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.6s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 3.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 4 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, 1, 0, 0].
