Free memory was 55.7 MB in the beginning and 54.7 MB in the end (delta: 1.0 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 3 terminating modules (0 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * d and consists of 6 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (out_len)] + -1 * s and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[s] + -1 * s and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.1s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 14.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 26.5ms AutomataMinimizationTime, 2 MinimizatonAttempts, 9 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 27 states and ocurred in iteration 1. Nontrivial modules had stage [3, 0, 0, 0, 0].
