YES(?,POLY)

'Pop* with parameter subtitution (timeout of 60.0 seconds)'
-----------------------------------------------------------
Answer:           YES(?,POLY)
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  and(tt(), X) -> X
     , plus(N, 0()) -> N
     , plus(N, s(M)) -> s(plus(N, M))}

Proof Output:    
  The input was oriented with the instance of POP* as induced by the precedence
  
   and ~ plus
  
  and safe mapping
  
   safe(and) = {}, safe(tt) = {}, safe(plus) = {}, safe(0) = {},
   safe(s) = {1} .
  
  For your convenience, here is the input in predicative notation:
  
   Rules:
    {  and(tt(), X;) -> X
     , plus(N, 0();) -> N
     , plus(N, s(; M);) -> s(; plus(N, M;))}
