- Strict TRS:
    ack(0(),y) -> s(y)
    ack(s(x),y) -> f(x,x)
    ack(s(x),0()) -> ack(x,s(0()))
    ack(s(x),s(y)) -> ack(x,ack(s(x),y))
    f(x,y) -> ack(x,y)
    f(x,s(y)) -> f(y,x)
    f(s(x),y) -> f(x,s(x))
- Signature:
    {ack/2,f/2} / {0/0,s/1}
- Obligation:
    innermost derivational complexity wrt. signature {0,ack,f,s}
The problem is still open.
