One deterministic module has affine ranking function (array_size + (-1 * i)) and consists of 5 locations. One deterministic module has affine ranking function ((-1 * pass) + n) and consists of 3 locations. One deterministic module has affine ranking function NULL and consists of 10 locations. One nondeterministic module has affine ranking function NULL and consists of 4 locations. 7 modules have a trivial ranking function, the largest among these consists of 19 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.5s and 12 iterations.
