MAYBE

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