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 4 terminating modules (1 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + length and consists of 5 locations. One deterministic module has 2-nested ranking function (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then 1 else 0), (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] else -8 * j + 4) and consists of 7 locations. One deterministic module has 2-nested ranking function (if length + -2 * unknown-#memory_int-unknown[arr][arr] > 0 then 1 else 0), (if length + -2 * unknown-#memory_int-unknown[arr][arr] > 0 then length + -2 * unknown-#memory_int-unknown[arr][arr] else -2 * j + unknown-#length-unknown[__builtin_alloca(length*sizeof(int))]) 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 5.8s and 5 iterations.
