We consider the following Problem:

  Strict Trs:
    {  a() -> g(c())
     , g(a()) -> b()
     , f(g(X), b()) -> f(a(), X)}
  StartTerms: basic terms
  Strategy: innermost

Certificate: YES(?,O(n^1))

Proof:
  Arguments of following rules are not normal-forms:
  {g(a()) -> b()}
  
  All above mentioned rules can be savely removed.
  
  We consider the following Problem:
  
    Strict Trs:
      {  a() -> g(c())
       , f(g(X), b()) -> f(a(), X)}
    StartTerms: basic terms
    Strategy: innermost
  
  Certificate: YES(?,O(n^1))
  
  Proof:
    The weightgap principle applies, where following rules are oriented strictly:
    
    TRS Component: {f(g(X), b()) -> f(a(), X)}
    
    Interpretation of nonconstant growth:
    -------------------------------------
      The following argument positions are usable:
        Uargs(g) = {}, Uargs(f) = {1}
      We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
      Interpretation Functions:
       a() = [0]
             [0]
       g(x1) = [0 0] x1 + [1]
               [0 0]      [1]
       c() = [0]
             [0]
       b() = [0]
             [0]
       f(x1, x2) = [1 0] x1 + [0 0] x2 + [0]
                   [0 0]      [0 0]      [1]
    
    The strictly oriented rules are moved into the weak component.

Hurray, we answered YES(?,O(n^1))
