One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function z and consists of 4 locations. One nondeterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.5s and 5 iterations.
