    + Considered Problem:

        - Signature:
            {active/1,f/1,if/3,proper/1,top/1} / {c/0,false/0,mark/1,ok/1,true/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {active,f,if,proper,top} and constructors {c,false,mark,ok
            ,true}

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