One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. One deterministic module has affine ranking function ((((long) 2 * y) + ((long) -2 * x)) + 1) and consists of 3 locations. One nondeterministic module has affine ranking function ((((long) 2 * y) + ((long) -2 * x)) + 1) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.8s and 5 iterations.
