Max. memory is 16.1 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 6 terminating modules (3 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op1 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op2 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 5 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.0s and 4 iterations.
