Term Rewriting System R: [X] f(X) -> g(n__h(n__f(X))) f(X) -> n__f(X) h(X) -> n__h(X) activate(n__h(X)) -> h(activate(X)) activate(n__f(X)) -> f(activate(X)) activate(X) -> X Termination of R to be shown. Removing the following rules from R which fullfill a polynomial ordering: activate(n__f(X)) -> f(activate(X)) where the Polynomial interpretation: POL(g(x_1)) = x_1 POL(activate(x_1)) = 2*x_1 POL(h(x_1)) = x_1 POL(f(x_1)) = 1 + x_1 POL(n__f(x_1)) = 1 + x_1 POL(n__h(x_1)) = x_1 was used. Not all Rules of R can be deleted, so we still have to regard a part of R.
