- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (1 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function -1 * i and consists of 6 locations. One deterministic module has affine ranking function -1 * i + n and consists of 3 locations. One deterministic module has affine ranking function 2 * i + -2 * j + 1 and consists of 4 locations. One nondeterministic module has affine ranking function 2 * i + -2 * j + 1 and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations.
