Max. memory is 16.1GB. * Witness Printer took 4.51ms. Allocated memory is still 197.1MB. Free memory is still 142.6MB. There was no memory consumed. 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 (3 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function ((-1 * i) + len) and consists of 3 locations. One deterministic module has affine ranking function ((2 * j) + 1) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.4s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 6.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 16 StatesRemovedByMinimization, 3 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, 0, 0, 0].
