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