Allocated memory is still 142.6MB. Free memory was 81.8MB in the beginning and 80.8MB 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 4 terminating modules (2 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * z + 100 and consists of 10 locations. One deterministic module has affine ranking function -1 * y + 100 and consists of 9 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.7s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 3.4s. Construction of modules took 0.1s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 2 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 [2, 0, 0, 0, 0].
