We consider the following Problem:

  Strict Trs:
    {  g(x, y) -> x
     , g(x, y) -> y
     , f(s(x), y, y) -> f(y, x, s(x))}
  StartTerms: basic terms

    The weightgap principle applies, where following rules are oriented strictly:
    
    TRS Component: {g(x, y) -> x}
    
    Interpretation of nonconstant growth:
    -------------------------------------
      The following argument positions are usable:
        Uargs(g) = {}, Uargs(f) = {}, Uargs(s) = {}
      We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
      Interpretation Functions:
       g(x1, x2) = [1 0] x1 + [0 0] x2 + [2]
                   [0 1]      [1 1]      [0]
       f(x1, x2, x3) = [0 0] x1 + [0 0] x2 + [1 1] x3 + [1]

               [0 0]      [0]
    
    The strictly oriented rules are moved into the weak component.
