Max. memory is 16.1 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 8 terminating modules (6 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 6 locations. 6 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 28.0s and 9 iterations.
