Term Rewriting System R: [x, y] f(x, x) -> a f(g(x), y) -> f(x, y) Termination of R to be shown. Removing the following rules from R which fullfill a polynomial ordering: f(x, x) -> a f(g(x), y) -> f(x, y) where the Polynomial interpretation: POL(g(x_1)) = 2 + x_1 POL(a) = 0 POL(f(x_1, x_2)) = 1 + x_1 + x_2 was used. All Rules of R can be deleted. Termination of R successfully shown. Duration: 0.352 seconds.
