How do computer adaptive tests work? What do the algorithms look like (more inside)?

I can find very general information about how tests like the GMAT CAT work, but I'm looking for something with a little more detail. Do the questions usually come from two or three difficulty "bins", or are they more analog? Is there academic theory out there about how many questions it takes to find a competency level or percentile?
Are any of the algorithms public?
