Allocated memory is still 174.1MB. Free memory was 131.9MB in the beginning and 130.9MB 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 (1 trivial, 4 deterministic, 2 nondeterministic). One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[d][d] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 7 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 5 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[d][d] and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.6s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 14.2s. Construction of modules took 0.1s. Büchi inclusion checks took 3.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
