Term Rewriting System R: [x, y] *(x, *(minus(y), y)) -> *(minus(*(y, y)), x) Termination of R to be shown. Removing the following rules from R which fullfill a polynomial ordering: *(x, *(minus(y), y)) -> *(minus(*(y, y)), x) where the Polynomial interpretation: POL(*(x_1, x_2)) = 2*x_1 + 2*x_2 POL(minus(x_1)) = 1 + x_1 was used. All Rules of R can be deleted. Termination of R successfully shown. Duration: 0.357 seconds.
