- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 8 terminating modules (0 trivial, 6 deterministic, 2 nondeterministic). One deterministic module has affine ranking function (k + ((long) -1 * z)) and consists of 5 locations. One deterministic module has affine ranking function (k + ((long) -1 * z)) and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function (((long) 2 * x) + 1) and consists of 5 locations. One deterministic module has affine ranking function (x + ((long) -1 * d)) and consists of 5 locations. One nondeterministic module has affine ranking function (y + ((long) -1 * d)) and consists of 5 locations. One nondeterministic module has affine ranking function ((long) y + 1) and consists of 5 locations.
