YES(?,POLY)

'Pop* with parameter subtitution (timeout of 60.0 seconds)'
-----------------------------------------------------------
Answer:           YES(?,POLY)
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  app(nil(), YS) -> YS
     , app(cons(X), YS) -> cons(X)
     , from(X) -> cons(X)
     , zWadr(nil(), YS) -> nil()
     , zWadr(XS, nil()) -> nil()
     , zWadr(cons(X), cons(Y)) -> cons(app(Y, cons(X)))
     , prefix(L) -> cons(nil())}

Proof Output:    
  The input was oriented with the instance of POP* as induced by the precedence
  
   app ~ from, app ~ zWadr, app ~ prefix, from ~ zWadr, from ~ prefix,
   zWadr ~ prefix
  
  and safe mapping
  
   safe(app) = {1, 2}, safe(nil) = {}, safe(cons) = {1},
   safe(from) = {}, safe(zWadr) = {1}, safe(prefix) = {} .
  
  For your convenience, here is the input in predicative notation:
  
   Rules:
    {  app(; nil(), YS) -> YS
     , app(; cons(; X), YS) -> cons(; X)
     , from(X;) -> cons(; X)
     , zWadr(YS; nil()) -> nil()
     , zWadr(nil(); XS) -> nil()
     , zWadr(cons(; Y); cons(; X)) -> cons(; app(; Y, cons(; X)))
     , prefix(L;) -> cons(; nil())}
