One deterministic module has affine ranking function ((-2 * i) + 19) and consists of 3 locations. One deterministic module has affine ranking function ((-2 * j) + 23) and consists of 3 locations. One nondeterministic module has affine ranking function ((-2 * j) + 23) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.2s and 7 iterations.
