MAYBE

'Pop* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  dx(X()) -> 1()
     , dx(0()) -> 0()
     , dx(1()) -> 0()
     , dx(a()) -> 0()
     , dx(+(f, g)) -> +(dx(f), dx(g))
     , dx(*(f, g)) -> +(*(dx(f), g), *(dx(g), f))
     , dx(-(f, g)) -> -(dx(f), dx(g))
     , dx(neg(f)) -> neg(dx(f))
     , dx(/(f, g)) -> -(/(dx(f), g), /(*(dx(g), f), exp(g, 2())))
     , dx(ln(f)) -> /(dx(f), f)
     , dx(exp(f, g)) ->
       +(*(dx(f), *(exp(f, -(g, 1())), g)),
         *(dx(g), *(exp(f, g), ln(f))))}

Proof Output:    
  The input cannot be shown compatible
