WORST_CASE(?,O(n^1))
* Step 1: NaturalPI WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            f(g(X)) -> f(X)
        - Signature:
            {f/1} / {g/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f} and constructors {g}
    + Applied Processor:
        NaturalPI {shape = Linear, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
    + Details:
        We apply a polynomial interpretation of kind constructor-based(linear):
        The following argument positions are considered usable:
          none
        
        Following symbols are considered usable:
          {f}
        TcT has computed the following interpretation:
          p(f) = 9 + 2*x1
          p(g) = 4 + x1  
        
        Following rules are strictly oriented:
        f(g(X)) = 17 + 2*X
                > 9 + 2*X 
                = f(X)    
        
        
        Following rules are (at-least) weakly oriented:
