WORST_CASE(?,O(n^1))
* Step 1: NaturalPI WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            f(x,y) -> g(x,y)
            g(h(x),y) -> h(f(x,y))
            g(h(x),y) -> h(g(x,y))
        - Signature:
            {f/2,g/2} / {h/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f,g} and constructors {h}
    + 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:
          uargs(h) = {1}
        
        Following symbols are considered usable:
          {f,g}
        TcT has computed the following interpretation:
          p(f) = 15 + 4*x1
          p(g) = 8 + 4*x1 
          p(h) = 5 + x1   
        
        Following rules are strictly oriented:
           f(x,y) = 15 + 4*x 
                  > 8 + 4*x  
                  = g(x,y)   
        
        g(h(x),y) = 28 + 4*x 
                  > 20 + 4*x 
                  = h(f(x,y))
        
        g(h(x),y) = 28 + 4*x 
                  > 13 + 4*x 
                  = h(g(x,y))
        
        
        Following rules are (at-least) weakly oriented:
