One deterministic module has affine ranking function NULL and consists of 5 locations. One deterministic module has affine ranking function (9 + (-2 * i)) and consists of 4 locations. One deterministic module has affine ranking function NULL and consists of 4 locations. 7 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 29.3s and 11 iterations.
