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 21 terminating modules (16 trivial, 5 deterministic, 0 nondeterministic). One deterministic module has affine ranking function 5 + -2 * var and consists of 5 locations. One deterministic module has affine ranking function 5 + -2 * var and consists of 4 locations. One deterministic module has affine ranking function 3 + -2 * var and consists of 4 locations. One deterministic module has affine ranking function 3 + -2 * var and consists of 4 locations. One deterministic module has affine ranking function 19 + -2 * i2 and consists of 3 locations. 16 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 56.9s and 17 iterations.
