- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 6 terminating modules (3 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 5 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations.
