One deterministic module has affine ranking function (((long long) -2 * op2) + 1) and consists of 6 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 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.6s and 4 iterations.
