One deterministic module has affine ranking function (k + (-1 * z)) and consists of 5 locations. One deterministic module has affine ranking function (k + (-1 * z)) and consists of 4 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function (x + (-1 * d)) and consists of 5 locations. One deterministic module has affine ranking function x and consists of 5 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function y and consists of 5 locations. One nondeterministic module has affine ranking function y and consists of 5 locations. One nondeterministic module has affine ranking function y and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.3s and 12 iterations.
