One deterministic module has affine ranking function (((long long) -2 * i) + 7) and consists of 8 locations. One deterministic module has affine ranking function (((long long) -2 * i) + 9) and consists of 6 locations. One nondeterministic module has affine ranking function (((long long) -2 * i) + 9) and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.5s and 5 iterations.
