Please find posted a selection of papers from the most recent (of last year) leading DB conferences. Pick one that you like. Some of you have already found a paper, and don't need to pick one from those posted. Of course, even so, they can still change mind and pick one from the posted instead. You should submit a report which will contain: 1. A short description of the problem studied in the paper you select. 2. Simple explanations of the intuition behind the algorithms in the paper. (Illustrate with simple examples.) 3. A list of things you *don't like* in the paper, either: (a) because you think it could be done better, or (b) because you didn't fully understand it. 4. If (a) provide a suggestion of how it can be done better or simpler. If (b) give your best guess about how it could be. Your report should be not more than 10 single-spaced pages. Additionally, you should prepare a 20 minute presentation. We will set two days (in April) for the presentations.
