MAYBE

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

Strict Trs:
  { ite(tt(), u, v) -> u
  , ite(ff(), u, v) -> v
  , find(u, v, []()) -> ff()
  , find(u, v, ::(::(u, v), E)) -> tt()
  , find(u, v, ::(::(u2, v2), E)) -> find(u, v, E)
  , complete(u, [](), E) -> tt()
  , complete(u, ::(v, S), E) ->
    ite(find(u, v, E), complete(u, S, E), ff())
  , clique([](), E) -> tt()
  , clique(::(u, K), E) -> ite(complete(u, K, E), clique(K, E), ff())
  , choice([](), K, E) -> ite(clique(K, E), K, []())
  , choice(::(u, S), K, E) -> choice(S, K, E)
  , choice(::(u, S), K, E) -> choice(S, ::(u, K), E) }
Obligation:
  innermost runtime complexity
