WORST_CASE(Omega(n^1),O(n^1))
* Step 1: Sum.  WORST_CASE(Omega(n^1),O(n^1))
    + Considered Problem:

        - Obligation:
             runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:

    + Applied Processor:
        DecreasingLoops {bound = AnyLoop, narrow = 10}
    + Details:
        The system has following decreasing Loops:
          rev(y){y -> ++(x,y)} =
            rev(++(x,y)) ->^+ ++(rev(y),rev(x))

        - Strict TRS:
            rev(++(x,x)) -> rev(x)

        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 1.
        The enriched problem is compatible with follwoing automaton.

        The problem is already closed. The intended complexity is O(1).
