WORST_CASE(?,O(n^2))
* Step 1: NaturalPI WORST_CASE(?,O(n^2))
    + Considered Problem:
        - Strict TRS:
            *(x,*(y,z)) -> *(otimes(x,y),z)
            *(x,oplus(y,z)) -> oplus(*(x,y),*(x,z))
            *(+(x,y),z) -> oplus(*(x,z),*(y,z))
            *(1(),y) -> y
        - Signature:
            {*/2} / {+/2,1/0,oplus/2,otimes/2}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {*} and constructors {+,1,oplus,otimes}
    + Applied Processor:
        NaturalPI {shape = Mixed 2, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
    + Details:
        We apply a polynomial interpretation of kind constructor-based(mixed(2)):
        The following argument positions are considered usable:
          uargs(oplus) = {1,2}
        
        Following symbols are considered usable:
          {*}
        TcT has computed the following interpretation:
               p(*) = 1 + x1 + x1*x2 + 3*x2
               p(+) = 3 + x1 + x2          
               p(1) = 1                    
           p(oplus) = 1 + x1 + x2          
          p(otimes) = x1 + x2              
        
        Following rules are strictly oriented:
            *(x,*(y,z)) = 4 + 2*x + x*y + x*y*z + 3*x*z + 3*y + 3*y*z + 9*z
                        > 1 + x + x*z + y + y*z + 3*z                      
                        = *(otimes(x,y),z)                                 
        
        *(x,oplus(y,z)) = 4 + 2*x + x*y + x*z + 3*y + 3*z                  
                        > 3 + 2*x + x*y + x*z + 3*y + 3*z                  
                        = oplus(*(x,y),*(x,z))                             
        
            *(+(x,y),z) = 4 + x + x*z + y + y*z + 6*z                      
                        > 3 + x + x*z + y + y*z + 6*z                      
                        = oplus(*(x,z),*(y,z))                             
        
               *(1(),y) = 2 + 4*y                                          
                        > y                                                
                        = y                                                
        
        
        Following rules are (at-least) weakly oriented:
