We are asked to determine termination of the following first-order TRS. 0 : [] --> o 1 : [] --> o f : [o * o * o] --> o g : [o * o] --> o h : [o] --> o f(0, 1, X) => f(h(X), h(X), X) h(0) => 0 h(g(X, Y)) => Y As the system is orthogonal, it is terminating if it is innermost terminating by [Gra95]. Then, by [FuhGieParSchSwi11], it suffices to prove (innermost) termination of the typed system, with sort annotations chosen to respect the rules, as follows: 0 : [] --> aa 1 : [] --> aa f : [aa * aa * aa] --> r g : [aa * aa] --> aa h : [aa] --> aa +++ Citations +++ [FuhGieParSchSwi11] C.
