* Step 1: Bounds WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            b(r(x)) -> r(b(x))
            w(r(x)) -> r(w(x))
        - Signature:
            {b/1,w/1} / {r/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {b,w} and constructors {r}
    + Applied Processor:
        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 1.
        The enriched problem is compatible with follwoing automaton.

* Step 2: EmptyProcessor WORST_CASE(?,O(1))
    + Considered Problem:
        - Weak TRS:
            b(r(x)) -> r(b(x))
            w(r(x)) -> r(w(x))
        - Signature:
            {b/1,w/1} / {r/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {b,w} and constructors {r}
    + Applied Processor:
        EmptyProcessor
    + Details:
        The problem is already closed. The intended complexity is O(1).
