- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (((long) 2 * x) + 1) and consists of 4 locations. One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 5 locations. One nondeterministic module has affine ranking function (((long) -1 * y) + x) and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations.
