15.99/11.17	  - StatisticsResult: Constructed decomposition of program
15.99/11.17	    Your program was decomposed into 3 terminating modules (2 trivial, 0 deterministic, 1 nondeterministic). One nondeterministic module has affine ranking function \old(ls) and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations.
