YES We show the termination of the TRS R: f(s(X),Y) -> h(s(f(h(Y),X))) -- SCC decomposition. Consider the dependency pair problem (P, R), where P consists of p1: f#(s(X),Y) -> f#(h(Y),X) and R consists of: r1: f(s(X),Y) -> h(s(f(h(Y),X))) The estimated dependency graph contains the following SCCs: (no SCCs)
