Allocated memory is still 209.7MB. Free memory was 166.8MB in the beginning and 165.7MB in the end (delta: 1.0MB). There was no memory consumed. 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 7 terminating modules (3 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 9 locations. One deterministic module has affine ranking function aux-x_ref-aux + -1 * aux-y_ref-aux and consists of 3 locations. One nondeterministic module has affine ranking function aux-x_ref-aux + -1 * unknown-#memory_int-unknown[y_ref][y_ref] and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.2s and 8 iterations. TraceHistogramMax:4. Analysis of lassos took 18.8s. Construction of modules took 0.2s. Büchi inclusion checks took 2.9s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 26 StatesRemovedByMinimization, 4 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, 1, 0, 0].
