For your initial reaction post, focus on how heuristics are tailored for specific problems. Are there standard heuristics? are there specific ones? why? do they make sense? Is there any heuristic that you would add to any of the papers? is it easy to measure?

Do include some of the learning from the mandatory reading part and connect with one or more of the articles listed.  Make sure you include references/sources in your posts.
