Instructors for combinatorial algorithms courses around the world are putting lecture notes and other interesting material on the WWW for their classes, but there is no reason the rest of the world shouldn't benefit as well. Below are the best course sites we have found to date. A similar collection of algorithm courses is being maintained by Kirk Pruhs at Univ. of Pittsburgh.
Feel free to look around. If you find something useful, then drop us a line to let us know what we did right. If you're looking for something that's not here yet, drop us a line and tell us that too. We're looking for as many good implementations as we can find -- so if you have an implementation for a specific problem, or know where one can be found, let us know and we'll see if we can't get it attached to the site.
This algorithms repository is part of the ongoing algorithms-related research conducted here in the Department of Computer Science at the State University of New York at Stony Brook.
