* Step 1: Bounds WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            minus(f(x,y)) -> f(minus(y),minus(x))
            minus(h(x)) -> h(minus(x))
            minus(minus(x)) -> x
        - Signature:
            {minus/1} / {f/2,h/1}
        - Obligation:
             runtime complexity wrt. defined symbols {minus} and constructors {f,h}
    + Applied Processor:
        Bounds {initialAutomaton = perSymbol, 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:
            minus(f(x,y)) -> f(minus(y),minus(x))
            minus(h(x)) -> h(minus(x))

    + Applied Processor:
        EmptyProcessor
    + Details:
        The problem is already closed. The intended complexity is O(1).
