Tool for viewing sleep data

The fine folks at Zeo invited me to participate in a polyphasic sleep experiment, and of course I was thrilled to do it. I've put together a little tool in python for parsing the output from their hardware. First, the pretty pictures: I'm nearly satisfied with the results (though I don't understand where the doubling

In which the optimizer eats itself, part I

A vanilla PSO algorithm has a handful of tunable parameters which affect the convergence rate. For our purposes, we're going to consider the set \{ \omega, c_1, c_2, n_{\mathrm{particles}} \} to be our set of adjustable parameters. It is certainly true that the bounds on both position and velocity for each particle will affect convergence,
