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 3 terminating modules (1 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * s and consists of 6 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * s and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.2s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 4.7s. 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 2. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 3 StatesRemovedByMinimization, 1 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].
