The TRS R consists of the following rules:

Used ordering:
Polynomial interpretation [POLO]:

   POL(U11(x_1)) = 2 + x_1
   POL(U12(x_1)) = 2*x_1
   POL(__(x_1, x_2)) = 2 + x_1 + x_2

With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:
