Free memory was 141.2MB in the beginning and 140.2MB in the end (delta: 1.1MB). Peak memory consumption was 2.1MB. 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 (6 trivial, 6 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op6 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function 1 + -2 * op8 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. 6 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.1s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 4.1s. Construction of modules took 0.1s. Büchi inclusion checks took 2.1s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
