* Step 1: WeightGap WORST_CASE(?,O(n^2))
    + Considered Problem:
        - Strict TRS:

        WeightGap {wgDimension = 1, wgDegree = 1, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
    + Details:
        The weightgap principle applies using the following nonconstant growth matrix-interpretation:
          We apply a matrix interpretation of kind constructor based matrix interpretation:
          The following argument positions are considered usable:
            uargs(f) = {2},
            uargs(s) = {1}
          
          Following symbols are considered usable:

          TcT has computed the following interpretation:
            p(c) = [1] x1 + [14]
            p(f) = [1] x2 + [0] 
            p(s) = [1] x1 + [2] 
          
          Following rules are strictly oriented:
          f(x,c(y)) = [1] y + [14]  
                    > [1] y + [2]   
                    = f(x,s(f(y,y)))
          
          
          Following rules are (at-least) weakly oriented:
          f(s(x),s(y)) =  [1] y + [2]    
                       >= [1] y + [18]   
                       =  f(x,s(c(s(y))))
          
        Further, it can be verified that all rules not oriented are covered by the weightgap condition.
