The 7-piece suicide checkers database
Last week, I computed the 7-piece suicide checkers database. First, I changed my database generator so that it can now also compute databases with more than 4 pieces per side. For suicide checkers this is necessary, since positions with e.g. 6-1 pieces are not clear at all, they might be either a win or a loss (no draws, I think). The 7-piece database took 2 days to generate, and in compressed form it is 2GB large. That is much larger than the regular 7-piece database. I probably won't build the 8-piece suicide database, it will be huge in compressed form and practically unusable. I have restarted my suicide book generator again from scratch, with the larger database the book it generates should be much improved.
