One deterministic module has affine ranking function x and consists of 6 locations. One deterministic module has affine ranking function a and consists of 4 locations. One deterministic module has affine ranking function a and consists of 7 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.5s and 5 iterations.
