    + Considered Problem:
        - Strict TRS:

        - Obligation:
            innermost runtime complexity wrt. defined symbols {f,g,top} and constructors {active,mark,ok,proper}
    + Applied Processor:
        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 1.
        The enriched problem is compatible with follwoing automaton.
