- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 6 terminating modules (2 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (y + (-1 * x)) and consists of 5 locations. One deterministic module has affine ranking function (y + (-1 * x)) and consists of 3 locations. One deterministic module has affine ranking function ((-1 * y) + x) and consists of 3 locations. One nondeterministic module has affine ranking function ((-1 * y) + x) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations.
