Peak memory consumption was 34.4MB. Max. memory is 16.1GB. * Witness Printer took 10.93ms. Allocated memory is still 283.1MB. Free memory is still 206.7MB. 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 (1 trivial, 6 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (k + ((long long) -1 * z)) and consists of 4 locations. One deterministic module has affine ranking function (k + ((long long) -1 * z)) and consists of 4 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function (((long long) 2 * x) + 1) and consists of 5 locations. One deterministic module has affine ranking function x 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 8.6s and 8 iterations. TraceHistogramMax:1. Analysis of lassos took 7.5s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 4.
