MAYBE

'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost relative runtime-complexity with respect to
  Strict Rules: {a() -> b()}
  Weak Rules: {f(x, y) -> f(a(), f(b(), b()))}

Proof Output:    
  EPO* only applicable for innermost runtime complexity analysis of constructor TRSs
