TIMEOUT We are left with following problem, upon which TcT provides the certificate TIMEOUT. Strict Trs: { from(X) -> cons(X, from(s(X))) , sel(s(X), cons(Y, Z)) -> sel(X, Z) , sel(0(), cons(X, Y)) -> X } Obligation: innermost runtime complexity Answer: TIMEOUT Computation stopped due to timeout after 10.0 seconds. Arrrr..
