One deterministic module has affine ranking function ((long long) -1 * \old(m)) and consists of 5 locations. One deterministic module has affine ranking function ((long long) -1 * \old(m)) and consists of 6 locations. One deterministic module has affine ranking function ((long long) -1 * \old(m)) and consists of 5 locations. One deterministic module has affine ranking function \old(m) and consists of 6 locations. One deterministic module has affine ranking function \old(m) and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.9s and 6 iterations.
