One deterministic module has affine ranking function 2 * x + 1 and consists of 5 locations. One deterministic module has affine ranking function -1 * y + x and consists of 4 locations. One nondeterministic module has affine ranking function -1 * y + x and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.3s and 6 iterations.
