• Updated the Links page. Namely, added a link to an article at ComputorEdge about Billy and Daisy, and updated the link to the online Billy.

August 21, 2005

• Released Cotiro 0.2. This version is the first of many enhancement releases, each of which will add one feature and bring Cotiro closer to an end-user-ready product. This version adds the ability for some constraints in the system to be "soft", which means that the system will attempt to satisfy them, but if necessary it will explore other options.

February 22, 2005

• Released Cotiro 0.1, another new program. Cotiro was actually a research project into constraint satisfaction during my undergraduate studies. Given a set of courses, rooms, and teachers, Cotiro will produce a college time and room schedule, which take into account various constraints (like that a professor can only teach one class at a time).
• Also added a paper I wrote on the subject of Cotiro to the Writings section.

November 17, 2004

• Released GUSH 1.0. GUSH is actually a quite-old program of mine, but it has never before been publicly available. I'm going to try and put more of my non-Billy-related programs on this site, and GUSH is the first example of this. If you ever have to schedule college courses, check it out.
