One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 4 locations. One nondeterministic module has affine ranking function (((long) -1 * y) + x) and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.1s and 6 iterations.
