One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function (N + ((long) -1 * k)) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * j) + m) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 6 locations. One nondeterministic module has affine ranking function (N + ((long) -1 * k)) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -1 * j) + m) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.7s and 9 iterations.
