One deterministic module has affine ranking function (array_size + ((long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function (array_size + ((long) -1 * j)) and consists of 3 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.8s and 7 iterations.
