Term Rewriting System R: [x] f(a) -> f(b) f(x) -> g(x) g(b) -> g(a) Termination of R to be shown. Removing the following rules from R which fullfill a polynomial ordering: f(x) -> g(x) where the Polynomial interpretation: POL(b) = 0 POL(g(x_1)) = x_1 POL(a) = 0 POL(f(x_1)) = 1 + x_1 was used. Not all Rules of R can be deleted, so we still have to regard a part of R. This program has no overlaps, so it is sufficient to show innermost termination. R contains the following Dependency Pairs: F(a) -> F(b) G(b) -> G(a) R contains no SCCs. Termination of R successfully shown. Duration: 0.846 seconds.
