Peak memory consumption was 41.6 MB. Max. memory is 16.1 GB. * Witness Printer took 3.75 ms. Allocated memory is still 138.4 MB. Free memory is still 60.4 MB. There was no memory consumed. Max. memory is 16.1 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 1 terminating modules (0 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function \old(n) and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.1s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 3.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 0. Automata minimization No data available. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 0 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
