Max. memory is 16.1GB. * Witness Printer took 2.26ms. Allocated memory is still 130.0MB. Free memory was 79.2MB in the beginning and 78.2MB in the end (delta: 997.0kB). There was no memory consumed. 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 (7 trivial, 4 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * array + -4 * i + unknown-#length-unknown[\result] and consists of 5 locations. One deterministic module has affine ranking function len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function len + -1 * i and consists of 3 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 19 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 412.4s and 12 iterations.
