  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 4 terminating modules (3 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 7 locations.
