One deterministic module has affine ranking function \old(n) and consists of 4 locations. One deterministic module has affine ranking function n and consists of 9 locations. One deterministic module has affine ranking function n and consists of 7 locations. One nondeterministic module has affine ranking function n and consists of 9 locations. One nondeterministic module has affine ranking function \old(n) and consists of 5 locations. 5 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 29.2s and 7 iterations.
