If you've noticed that some of the workunits start with 'ps' those are for the new particle swarm
search that we just got working (genetic search starts with 'gs'). With the last update to the
binaries the resulting work units return a lot more information about what kind of search they
were run from, when they were generated and how they were generated, so we're going to be able
to really start studying whats going on in depth now.

As to what we're going to be working on while getting these new results, the plan is:
1. fix the remaining memory leaks in the astronomy code
2. Nate is going to be updating the code with the 'convolution' which will make work units a bit longer but more accurate
3. i'm going to be implementing adaptive simulated annealing and maybe parallel tempering and stochastic tunneling search methods
4. we'll be doing a lot of data analysis about the particle swarm searches and comparing those to the asynchronous genetic search
5. there's an upcoming genetic/evolutionary algorithms conference (paper submissions due by mid january) and we're hoping to submit
the results for genetic search (and particle swarm if we have enough) to that.

thanks again everyone for crunching our numbers and putting up with all the server troubles last week. :D
