- Strict TRS:
    ack(0(),x) -> s(x)
    ack(s(x),0()) -> ack(x,s(0()))
    ack(s(x),s(y)) -> ack(x,ack(s(x),y))
    d(x) -> if(le(x,nr()),x)
    if(false(),x) -> nil()
    if(true(),x) -> cons(x,d(s(x)))
    le(0(),y) -> true()
    le(s(x),0()) -> false()
    le(s(x),s(y)) -> le(x,y)
    nr() -> ack(s(s(s(s(s(s(0())))))),0())
    numbers() -> d(0())
- Signature:
    {ack/2,d/1,if/2,le/2,nr/0,numbers/0} / {0/0,cons/2,false/0,nil/0,s/1,true/0}
- Obligation:
    innermost derivational complexity wrt. signature {0,ack,cons,d,false,if,le,nil,nr,numbers,s,true}
The problem is still open.
