TIMEOUT

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

Strict Trs:
  { fib(N) -> sel(N, fib1(s(0()), s(0())))
  , sel(s(N), cons(X, XS)) -> sel(N, activate(XS))
  , sel(0(), cons(X, XS)) -> X
  , fib1(X, Y) -> cons(X, n__fib1(Y, add(X, Y)))
  , fib1(X1, X2) -> n__fib1(X1, X2)
  , add(s(X), Y) -> s(add(X, Y))
  , add(0(), X) -> X
  , activate(X) -> X
  , activate(n__fib1(X1, X2)) -> fib1(X1, X2) }
Obligation:
  innermost runtime complexity
Answer:
  TIMEOUT

Computation stopped due to timeout after 10.0 seconds.

Arrrr..
