One deterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One deterministic module has affine ranking function (201 + ((long) -2 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One nondeterministic module has affine ranking function c and consists of 3 locations. One nondeterministic module has affine ranking function (221 + ((long) -2 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function x and consists of 9 locations. One nondeterministic module has affine ranking function x and consists of 14 locations. One nondeterministic module has affine ranking function c and consists of 8 locations. 5 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.7s and 11 iterations.
