Some Source code

• Splay tree code: This is an implementation of Tarjan and Sleator's splay tree algorithm, a self-adjusting binary search tree. I'm working on docs but the code is pretty easy to use. It should compile with just about any ANSI C compiler. Amortized log(n) performance.
• Rectangle Access Trees: This is an implementation of a suite of routines for dealing with rectangles in a 2D plane. Why rectangles? Well, it's nice if you are doing image manipulation, it is a natural way of representing image blobs or regions, and that's the one I managed to find a nice algorithm for. The problem was that I needed dynamic insertion and deletion in O(log(n)) time, plus I wanted to do range queries in sub-linear time. (Well, in the worst case it's obviously not possible, since a range query can return everything in your tree, but the time spent limiting the search is sub-linear.) For a description of the algorithm, check out the paper. This one actually has some man pages and other misc. documentation. This set of software includes the Splay tree code above, and makes heavy use of it.
• Combinatorial graphs code: Some code that embeds graphs into the combinatorial form. I did this for an algorithms class, so it may or may not be useful to you. Allows you to get the genus of a graph, and compute the connected components. If it is illegal to operate a Ponzi scheme, can we force the government via lawsuit to operate Social Security as a true trust fund, and not just another pyramid scheme? Better yet, can we force Congress through the courts to operate on a perpetual balanced budget? Worth looking into, seeing as how the balanced budget amendment looks like it will never pass. Isn't it about time this country elected a president who was a leader?
