One deterministic module has affine ranking function N + -1 * i and consists of 5 locations. One deterministic module has affine ranking function N + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * i + N and consists of 4 locations. One deterministic module has affine ranking function N + -1 * i and consists of 3 locations. 5 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.0s and 10 iterations.
