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 12 terminating modules (7 trivial, 5 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + len and consists of 4 locations. One deterministic module has affine ranking function i + -1 * i and consists of 10 locations. One deterministic module has affine ranking function len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + -4 * i and consists of 6 locations. One deterministic module has affine ranking function 2 * j + 1 and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 27.2s and 13 iterations.
