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 9 terminating modules (2 trivial, 7 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i1 + N1 and consists of 5 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function -1 * i2 + N2 and consists of 4 locations. One deterministic module has affine ranking function -1 * j1 + M1 and consists of 4 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function M2 + -1 * j2 and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 41.7s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 6.2s. Construction of modules took 0.2s. Büchi inclusion checks took 12.3s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 8. Automata minimization 8.3s AutomataMinimizationTime, 8 MinimizatonAttempts, 85906 StatesRemovedByMinimization, 8 NontrivialMinimizations. Non-live state removal took 15.3s Buchi closure took 0.2s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [7, 0, 0, 0, 0].
