    + Considered Problem:

        - Signature:
            {active/1,g/1,h/1,proper/1,top/1} / {c/0,d/0,mark/1,ok/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {active,g,h,proper,top} and constructors {c,d,mark,ok}

        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 4.
        The enriched problem is compatible with follwoing automaton.
