One deterministic module has affine ranking function (array_size + ((long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function j and consists of 5 locations. One nondeterministic module has affine ranking function j and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.6s and 6 iterations.
