Term Rewriting System R: [x] f(s(x)) -> f(g(x, x)) g(0, 1) -> s(0) 0 -> 1 Innermost Termination of R to be shown. Removing the following rules from R which left hand sides contain non normal subterms g(0, 1) -> s(0) Removing the following rules from R which fullfill a polynomial ordering: f(s(x)) -> f(g(x, x)) where the Polynomial interpretation: POL(g(x_1, x_2)) = x_1 + x_2 POL(1) = 0 POL(s(x_1)) = 1 + 2*x_1 POL(f(x_1)) = 2 + x_1 POL(0) = 0 was used. Not all Rules of R can be deleted, so we still have to regard a part of R. Removing the following rules from R which fullfill a polynomial ordering: 0 -> 1 where the Polynomial interpretation: POL(1) = 0 POL(0) = 1 was used. All Rules of R can be deleted. Innermost Termination of R successfully shown. Duration: 0.371 seconds.
