WORST_CASE(Omega(n^1),O(n^1))
* Step 1: Sum WORST_CASE(Omega(n^1),O(n^1))
    + Considered Problem:
        - Strict TRS:
            *(x,+(y,z)) -> +(*(x,y),*(x,z))
        - Signature:
            {*/2} / {+/2}
        - Obligation:
             runtime complexity wrt. defined symbols {*} and constructors {+}
    + Applied Processor:
        Sum {left = someStrategy, right = someStrategy}
    + Details:
        ()
** Step 1.a:1: DecreasingLoops WORST_CASE(Omega(n^1),?)
    + Considered Problem:
        - Strict TRS:
            *(x,+(y,z)) -> +(*(x,y),*(x,z))
        - Signature:
            {*/2} / {+/2}
        - Obligation:
             runtime complexity wrt. defined symbols {*} and constructors {+}
    + Applied Processor:
        DecreasingLoops {bound = AnyLoop, narrow = 10}
    + Details:
        The system has following decreasing Loops:
          *(x,y){y -> +(y,z)} =
            *(x,+(y,z)) ->^+ +(*(x,y),*(x,z))
              = C[*(x,y) = *(x,y){}]

** Step 1.b:1: NaturalMI WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            *(x,+(y,z)) -> +(*(x,y),*(x,z))
        - Signature:
            {*/2} / {+/2}
        - Obligation:
             runtime complexity wrt. defined symbols {*} and constructors {+}
    + Applied Processor:
        NaturalMI {miDimension = 1, miDegree = 1, miKind = Algebraic, uargs = UArgs, urules = URules, selector = Just any strict-rules}
    + Details:
        We apply a matrix interpretation of kind constructor based matrix interpretation:
        The following argument positions are considered usable:
          uargs(+) = {1,2}
        
        Following symbols are considered usable:
          all
        TcT has computed the following interpretation:
          p(*) = [2] x2 + [0]         
          p(+) = [1] x1 + [1] x2 + [8]
        
        Following rules are strictly oriented:
        *(x,+(y,z)) = [2] y + [2] z + [16]
                    > [2] y + [2] z + [8] 
                    = +(*(x,y),*(x,z))    
        
        
        Following rules are (at-least) weakly oriented:
        
** Step 1.b:2: EmptyProcessor WORST_CASE(?,O(1))
    + Considered Problem:
        - Weak TRS:
            *(x,+(y,z)) -> +(*(x,y),*(x,z))
        - Signature:
            {*/2} / {+/2}
        - Obligation:
             runtime complexity wrt. defined symbols {*} and constructors {+}
    + Applied Processor:
        EmptyProcessor
    + Details:
        The problem is already closed. The intended complexity is O(1).
