- Strict TRS:
    f(0(),y,0(),u) -> true()
    f(0(),y,s(z),u) -> false()
    f(s(x),0(),z,u) -> f(x,u,minus(z,s(x)),u)
    f(s(x),s(y),z,u) -> if(le(x,y),f(s(x),minus(y,x),z,u),f(x,u,z,u))
    if(false(),x,y) -> y
    if(true(),x,y) -> x
    le(0(),y) -> true()
    le(s(x),0()) -> false()
    le(s(x),s(y)) -> le(x,y)
    minus(0(),y) -> 0()
    minus(s(x),0()) -> s(x)
    minus(s(x),s(y)) -> minus(x,y)
    perfectp(0()) -> false()
    perfectp(s(x)) -> f(x,s(0()),s(x),s(x))
- Signature:
    {f/4,if/3,le/2,minus/2,perfectp/1} / {0/0,false/0,s/1,true/0}
- Obligation:
    innermost derivational complexity wrt. signature {0,f,false,if,le,minus,perfectp,s,true}
The problem is still open.
