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 12 terminating modules (7 trivial, 5 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * array + -4 * i + unknown-#length-unknown[\result] and consists of 5 locations. One deterministic module has affine ranking function ldv_global_msg_list + -4 * i + 1 and consists of 13 locations. One deterministic module has affine ranking function len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + -4 * i and consists of 6 locations. One deterministic module has affine ranking function r + 2 * j and consists of 4 locations. 7 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 26.0s and 13 iterations. TraceHistogramMax:2. Analysis of lassos took 23.6s. Construction of modules took 0.3s. Büchi inclusion checks took 1.8s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 7. Automata minimization 0.1s AutomataMinimizationTime, 11 MinimizatonAttempts, 111 StatesRemovedByMinimization, 10 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 [5, 0, 0, 0, 0].
