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 11 terminating modules (4 trivial, 2 deterministic, 5 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[A] + -4 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * j + l2 and consists of 4 locations. One nondeterministic module has affine ranking function -8 * j + 3 * unknown-#length-unknown[__builtin_alloca (Blen * sizeof(int))] and consists of 7 locations. One nondeterministic module has affine ranking function -8 * j + 5 * unknown-#length-unknown[__builtin_alloca (Blen * sizeof(int))] and consists of 8 locations. One nondeterministic module has affine ranking function -8 * j + 7 * unknown-#length-unknown[B] and consists of 9 locations. One nondeterministic module has affine ranking function -8 * j + 9 * unknown-#length-unknown[__builtin_alloca (Blen * sizeof(int))] and consists of 10 locations. One nondeterministic module has affine ranking function -1 * j + l2 and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 26.3s and 12 iterations.
