Term Rewriting System R:

   [x, y]
   -(-(neg(x), neg(x)), -(neg(y), neg(y))) -> -(-(x, y), -(x, y))

Termination of R to be shown.


Removing the following rules from R which fullfill a polynomial ordering: 

   -(-(neg(x), neg(x)), -(neg(y), neg(y))) -> -(-(x, y), -(x, y))

where the Polynomial interpretation:
POL(-(x_1, x_2)) = 1 + x_1 + x_2
POL(neg(x_1)) = 1 + x_1
was used. 



All Rules of R can be deleted.
