Problem:
 Equations:
  
 TRS:
  zero(sharp()) -> sharp()
  plusAC(x,sharp()) -> x
  plusAC(zero(x),zero(y)) -> zero(plusAC(x,y))
  plusAC(zero(x),one(y)) -> one(plusAC(x,y))
  plusAC(one(x),one(y)) -> zero(plusAC(x,plusAC(y,one(sharp()))))

Proof:
 AC-KBO Processor:
  precedence:
   one > plusAC > zero ~ sharp
   weight function:
    [one](x0) = x0 + 5,
    
    [zero](x0) = x0 + 1,
    
    [sharp] = 2,
    
    [plusAC](x0, x1) = x0 + x1 + 1
