- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * y + unknown-#memory_int-unknown[x_ref][x_ref] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y_ref][y_ref] + -1 * z and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] + -1 * unknown-#memory_int-unknown[y_ref][y_ref] and consists of 7 locations. 2 modules have a trivial ranking function, the largest among these consists of 14 locations.
