* Step 1: Bounds WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            active(cons(X1,X2)) -> cons(active(X1),X2)
            active(incr(X)) -> incr(active(X))
            active(incr(cons(X,XS))) -> mark(cons(s(X),incr(XS)))
            active(nats()) -> mark(cons(0(),incr(nats())))
            active(odds()) -> mark(incr(pairs()))
            active(pairs()) -> mark(cons(0(),incr(odds())))
            active(s(X)) -> s(active(X))
            cons(mark(X1),X2) -> mark(cons(X1,X2))
            cons(ok(X1),ok(X2)) -> ok(cons(X1,X2))
            head(mark(X)) -> mark(head(X))
            head(ok(X)) -> ok(head(X))
            incr(mark(X)) -> mark(incr(X))
            incr(ok(X)) -> ok(incr(X))
            proper(0()) -> ok(0())
            proper(cons(X1,X2)) -> cons(proper(X1),proper(X2))
            proper(incr(X)) -> incr(proper(X))
            proper(nats()) -> ok(nats())
            proper(odds()) -> ok(odds())
            proper(pairs()) -> ok(pairs())
            proper(s(X)) -> s(proper(X))
            s(mark(X)) -> mark(s(X))
            s(ok(X)) -> ok(s(X))
            tail(mark(X)) -> mark(tail(X))
            tail(ok(X)) -> ok(tail(X))
            top(mark(X)) -> top(proper(X))
            top(ok(X)) -> top(active(X))
        - Signature:
            {active/1,cons/2,head/1,incr/1,proper/1,s/1,tail/1,top/1} / {0/0,mark/1,nats/0,odds/0,ok/1,pairs/0}
        - Obligation:
             runtime complexity wrt. defined symbols {active,cons,head,incr,proper,s,tail,top} and constructors {0,mark
            ,nats,odds,ok,pairs}
    + Applied Processor:
        Bounds {initialAutomaton = perSymbol, enrichment = match}
    + Details:
        The problem is match-bounded by 9.
        The enriched problem is compatible with follwoing automaton.

        - Obligation:
             runtime complexity wrt. defined symbols {active,cons,head,incr,proper,s,tail,top} and constructors {0,mark
            ,nats,odds,ok,pairs}

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