Term Rewriting System R: [X, Y] f(s(X), Y) -> h(s(f(h(Y), X))) Termination of R to be shown. Removing the following rules from R which fullfill a polynomial ordering: f(s(X), Y) -> h(s(f(h(Y), X))) where the Polynomial interpretation: POL(s(x_1)) = 1 + x_1 POL(h(x_1)) = x_1 POL(f(x_1, x_2)) = 2*x_1 + 2*x_2 was used. All Rules of R can be deleted. Termination of R successfully shown. Duration: 0.360 seconds.
