YES(?,POLY)

'Pop* with parameter subtitution (timeout of 60.0 seconds)'
-----------------------------------------------------------
Answer:           YES(?,POLY)
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  add(0(), x) -> x
     , add(s(x), y) -> s(add(x, y))
     , mult(0(), x) -> 0()
     , mult(s(x), y) -> add(y, mult(x, y))}

Proof Output:    
  The input was oriented with the instance of POP* as induced by the precedence
  
   mult > add
  
  and safe mapping
  
   safe(add) = {2}, safe(0) = {}, safe(s) = {1}, safe(mult) = {} .
  
  For your convenience, here is the input in predicative notation:
  
   Rules:
    {  add(0(); x) -> x
     , add(s(; x); y) -> s(; add(x; y))
     , mult(0(), x;) -> 0()
     , mult(s(; x), y;) -> add(y; mult(x, y;))}
