One deterministic module has affine ranking function (((long) -2 * i) + 5) and consists of 4 locations. One deterministic module has affine ranking function (((long) -2 * i) + 7) and consists of 4 locations. One deterministic module has affine ranking function (((long) -2 * j) + 19) and consists of 2 locations. One nondeterministic module has affine ranking function (((long) -2 * j) + 19) and consists of 2 locations. 2 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.5s and 5 iterations.
