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, 3 deterministic, 4 nondeterministic). One deterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One deterministic module has affine ranking function (201 + ((long) -2 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One nondeterministic module has affine ranking function c and consists of 3 locations. One nondeterministic module has affine ranking function (221 + ((long) -2 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function c and consists of 8 locations. 4 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.2s and 9 iterations.
