One deterministic module has affine ranking function -1 * i1 + n and consists of 6 locations. One deterministic module has affine ranking function -1 * j1 + m and consists of 5 locations. One deterministic module has affine ranking function -1 * i2 + n and consists of 5 locations. One nondeterministic module has affine ranking function -1 * j1 + m and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.6s and 5 iterations.
