TIMEOUT We are left with following problem, upon which TcT provides the certificate TIMEOUT. Strict Trs: { quot(x, 0(), s(z)) -> s(quot(x, plus(z, s(0())), s(z))) , quot(0(), s(y), s(z)) -> 0() , quot(s(x), s(y), z) -> quot(x, y, z) , plus(0(), y) -> y , plus(s(x), y) -> s(plus(x, y)) } Obligation: innermost runtime complexity Answer: TIMEOUT Computation stopped due to timeout after 10.0 seconds. Arrrr..
