I got a 404 on everything related to that but I managed to get a pdf out of google's cache, not sure if it is just me, but I've attached it here. I've only read bits and pieces of it, it does seem pretty interesting. It also seems like something that you wouldn't really able to hand author bots for easily. Another thing I noticed was the relatively fast results they were getting. Their data shows a large increase in ability from .5 to 2 million cycles. Most of our bots take a lot longer for a large competitive increase.
