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 (1 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[ps] + -1 * pt and consists of 6 locations. One deterministic module has affine ranking function -1 * ps + unknown-#length-unknown[nondetString1] and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * pt and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.0s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 12.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 5 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 [3, 0, 0, 0, 0].
