TIMEOUT We are left with following problem, upon which TcT provides the certificate TIMEOUT. Strict Trs: { f(X) -> cons(X, n__f(n__g(X))) , f(X) -> n__f(X) , g(X) -> n__g(X) , g(0()) -> s(0()) , g(s(X)) -> s(s(g(X))) , sel(0(), cons(X, Y)) -> X , sel(s(X), cons(Y, Z)) -> sel(X, activate(Z)) , activate(X) -> X , activate(n__f(X)) -> f(activate(X)) , activate(n__g(X)) -> g(activate(X)) } Obligation: innermost runtime complexity Answer: TIMEOUT Computation stopped due to timeout after 60.0 seconds. Arrrr..
