MAYBE

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

Strict Trs:
  { active(f(X, X)) -> mark(f(a(), b()))
  , active(f(X1, X2)) -> f(active(X1), X2)
  , active(b()) -> mark(a())
  , f(mark(X1), X2) -> mark(f(X1, X2))
  , f(ok(X1), ok(X2)) -> ok(f(X1, X2))
  , proper(f(X1, X2)) -> f(proper(X1), proper(X2))
  , proper(a()) -> ok(a())
  , proper(b()) -> ok(b())
  , top(mark(X)) -> top(proper(X))
  , top(ok(X)) -> top(active(X)) }
Obligation:
  innermost runtime complexity
