One deterministic module has affine ranking function -2 * i + 9 and consists of 6 locations. One deterministic module has affine ranking function -2 * i + 7 and consists of 4 locations. One deterministic module has affine ranking function -2 * j + 19 and consists of 3 locations. One nondeterministic module has affine ranking function -2 * j + 19 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.2s and 5 iterations.
