TIMEOUT We are left with following problem, upon which TcT provides the certificate TIMEOUT. Strict Trs: { intlist(nil()) -> nil() , intlist(cons(x, y)) -> cons(s(x), intlist(y)) , intlist(cons(x, nil())) -> cons(s(x), nil()) , int(x, x) -> cons(x, nil()) , int(s(x), s(y)) -> intlist(int(x, y)) , int(s(x), 0()) -> nil() , int(0(), s(y)) -> cons(0(), int(s(0()), s(y))) } Obligation: innermost runtime complexity Answer: TIMEOUT Computation stopped due to timeout after 60.0 seconds. Arrrr..
