One deterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One deterministic module has affine ranking function (201 + ((long) -2 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function (211 + ((long) -2 * x)) and consists of 3 locations. One nondeterministic module has affine ranking function x and consists of 3 locations. One nondeterministic module has affine ranking function (221 + ((long) -2 * x)) and consists of 4 locations.
