One deterministic module has affine ranking function -1 * i1 + N1 and consists of 4 locations. One deterministic module has affine ranking function -1 * i2 + N2 and consists of 3 locations. One deterministic module has affine ranking function -1 * j1 + M1 and consists of 3 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function counter and consists of 3 locations. One deterministic module has affine ranking function M2 + -1 * j2 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.3s and 8 iterations.
