Excerpts from the reviews recommending rejection
************************************************
"The paper is very well written, thought-provoking, and
addresses a fundamental issue in AI: how to flexibly represent and
reason with knowledge at different temporal grain sizes. I greatly
enjoyed reading this paper, and would very much like to see it
published."
"The topic addressed in the paper is extremely important and of interest to
both decision-theoretic planning and reinforcement learning communities.
I think the paper could potentially serve as a basic reference
to this topic in future."
"Hierarchical options: Why have the authors avoided this?"
"Options" must be clearly, succinctly, and unambiguously defined."
"...the section that defines Q-functions does not even mention Watkins
...and doesn't even call them Q-functions."
