To anyone who isn't retired (jon and maybe 2 other people?) and/or still cares somewhat about connect four. I'm working on a program that generates connect four stats that might be useful. Actually it's the same program as before just now I'm adding a stats feature. What type of stats? It will have 4 different kinds of stats, all of which will overlap. 1) It will give the percentage of time each move is correct. I predict 2/6 will be the highest, then 3/5, then 4, then 1/7. 4 would be the highest except there is only one middle column. I think 4 will be higher than 2 or 6 individually. 2) I will tell it to focus on certain starts, and as it plays more and more games (it will eventually play every possible game), it will update the percentages for each start, and will have different percentages for each ply. So for instance, say I tell it to look at 43 as one of the starts. Every position after 43, it will record who is winning or if it's a draw, and which moves are the right moves (using Vianiato). So once it's all done I'll be able to say for example, in any game that started out with 43, where say, 5 moves have been made, there is a 64% chance the game is a draw, 20% chance White is winning, and 16% chance Black is winning, and a 57% chance 4 is a correct move for Black. This wouldn't be useful in a position you already know, but in an unfamiliar game, it could help you play faster cuz you'll know which moves to look at first. 3) Win % or draw % based on which colors have what threats. Not very interesting but easy to do. 4) The one I'm most interested in: win % based on which spots each color has. So for instance, what are the percentages if White has b2 and c2. Or if White has b2 and Black has c2. All kinds of stuff, i have a long list so far. I just think it would be cool to be able to say things like, "White has c2 and e2 and 9 moves have been played and therefore there's a 53% chance he's winning and a 72% chance he needs to go 3 or 5 right now." What I want from you guys is suggestions for #1 and #4, with #4 being more important. For #1 you are allowed to make errors, they don't hafta be perfect starts. For #4, any combination you think is interesting, and it can be any number of spots, but preferably under 10. The 2 examples i gave focused on 2 spots. I think my list covers all the good 2-spot combos. So I'd like for you guys to think of 3-spots and higher. Try to avoid obvious things like, if White has d2 and d3 and d4. I already know the % for that would be stacked in White's favor. Or stacked for Black if Black has all those. Also, if you can think of more stats I should take, please tell. Once i have the stats (months from now) i'll post em here, and there will be a program that tells you move by move what the stats are. The book generator will only go up to 19 moves but I might let the stats go in the 20's. Alsooo if any of you can think of combos for other board sizes then by all means give them. I expect about 0 responses but that's okay lol. But really it would only take a few minutes, just think off the top of your head. If you want i'll post my list here but i don't think it's necessary.
