One deterministic module has affine ranking function ((2 * i) + 1) and consists of 3 locations. One deterministic module has affine ranking function (((2 * i) + (-2 * j)) + 1) and consists of 4 locations. One nondeterministic module has affine ranking function NULL and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.5s and 8 iterations.
