One deterministic module has affine ranking function *x_ref and consists of 5 locations. One deterministic module has affine ranking function *x_ref and consists of 8 locations. One deterministic module has affine ranking function NULL and consists of 10 locations. One deterministic module has affine ranking function NULL and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 17 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 56.4s and 7 iterations.
