One deterministic module has affine ranking function (((long long) -2 * op3) + 1) and consists of 4 locations. One deterministic module has affine ranking function (((long long) -2 * op6) + 1) and consists of 4 locations. One deterministic module has affine ranking function (((long long) -2 * splverifierCounter) + 7) and consists of 4 locations. One deterministic module has affine ranking function (1 + ((long long) -2 * op8)) and consists of 4 locations. 5 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.5s and 6 iterations.
