Keep this in mind when preparing your crib sheets. For the students that were in today's 9AM recitation... The A* equation I scribbled down off the top of my head towards the end of the recitation did not have the correct form. The correct form (in several permutations) is on page 3 of the F19 notes. It's also in Anderson section 10.3. All the discussion we had on A* still applies. - Mark Drela From howiek at MIT.EDU Tue Mar 30 11:06:56 2004 From: howiek at MIT.EDU (Howard Kleinwaks) Date: Tue, 30 Mar 2004 11:06:56 -0500 Subject: [Unified-mailman] submitting CP problems online Message-ID: Students, Remember to submit you entire CP problem (all parts) in a single .zip file.
