Free memory was 105.7MB in the beginning and 104.7MB 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 10 terminating modules (1 trivial, 5 deterministic, 4 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[y][y] and consists of 7 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 4 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[z][z] and consists of 6 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[x][x] and consists of 8 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 8 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[z][z] 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 32.3s and 11 iterations.
