- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 6 terminating modules (0 trivial, 6 deterministic, 0 nondeterministic). One deterministic module has affine ranking function \old(y1) and consists of 8 locations. One deterministic module has affine ranking function \old(y2) and consists of 7 locations. One deterministic module has affine ranking function \old(m) and consists of 10 locations. One deterministic module has affine ranking function -2 * \old(n) + 2 * \old(m) + 1 and consists of 11 locations. One deterministic module has affine ranking function \old(m) and consists of 11 locations. One deterministic module has affine ranking function \old(m) and consists of 11 locations.
