YES(?,POLY)
We consider the following Problem:
  Strict Trs:
    {  f(x, a()) -> x
     , f(x, g(y)) -> f(g(x), y)}
  StartTerms: basic terms
  Strategy: innermost
Certificate: YES(?,POLY)
Proof:
  The input was oriented with the instance of
  Polynomial Path Order (PS) as induced by the safe mapping
  
   safe(f) = {1}, safe(a) = {}, safe(g) = {1}
  
  and precedence
  
   empty .
  
  Following symbols are considered recursive:
  
   {f}
  
  The recursion depth is 1 .
  
  For your convenience, here are the oriented rules in predicative
  notation (possibly applying argument filtering):
  
   Strict DPs: {}
   Weak DPs  : {}
   Strict Trs:
     {  f(a(); x) -> x
