TIMEOUT

We are left with following problem, upon which TcT provides the
certificate TIMEOUT.

Strict Trs:
  { zeros() -> cons(0(), n__zeros())
  , zeros() -> n__zeros()
  , and(tt(), X) -> activate(X)
  , activate(X) -> X
  , activate(n__zeros()) -> zeros()
  , length(cons(N, L)) -> s(length(activate(L)))
  , length(nil()) -> 0() }
Obligation:
  innermost runtime complexity
Answer:
  TIMEOUT

Computation stopped due to timeout after 10.0 seconds.

Arrrr..
