Re:bug

The video works on my comp, but I failed to notice anything unusual. The quality is pretty poor, so perhaps a few words on the problem wouldn\'t harm :)<br><br>Post edited by: Lieven, at: 2008/03/20 23:36

Re:BL2 Bot Player

Just a quick comment. The tale of the distribution (not the start) definitely follows an exponential decay, as I pointed out in an earlier post. The Poisson distribution does work, but you need to reformulate it as a problem of \"how many restarts for X number of blocks\". Also not very ad...

Re:BL2 Bot Player

Ok this is quite convincing. The method doesn\'t work. I do apologise for all the time you spend on this flawed idea! Thank you so much for trying anyway. Now you might wonder why I haven\'t tried to fit the Poisson as you suggested. The reason is that the Poisson has only 1 parameter, and the best ...

Re:BL2 Bot Player

That is very strange indeed. Furthermore, the sum of the first three lines is 711594, which is higher than the new eval. So my original eval spends more time on the lower depths, yet it does worse? Strange.<br><br>Post edited by: Lieven, at: 2008/02/17 19:37

Re:BL2 Bot Player

Thanks for the plot, doesn\'t look terribly good :/ A last attempt: Summing the last number of the first three rows of your two tests, we get 689660 (/1000000) 693779 (/1000000) or a variability of 0.05%. I think this is pretty good. Perhaps this value could give as an indication? Say when this valu...

Re:BL2 Bot Player

Thanks a lot for this data, I will have to think about what they mean :) You write: The problem with params scanning is that we need a reliable estimation of the average. I don\'t think this is necessary, all that we need to know for param evaluation is whether a certain evaluation is better than an...

Re:BL2 Bot Player

Thanks for all the info. I am a bit surprised about the small convergence. Just for fun, if you have time could you run it again on a larger number, say 2.500.000 blocks? I am just curious to see the results. Perhaps this method tries to extract too much detailed information from one run. A similar ...

Re:BL2 Bot Player

Thanks a lot, this looks great! 1 => 0.015544(F1) 0.29102 0.69344 2 => 0.30593 0.48459 0.20948 3 => 0.53528 0.35007 0.11464 Basically, I think the three first lines are enough, and the remaining lines are equal to the third (theoretically). One comment: In your table, the 9th and 10th row should hav...

Re:BL2 Bot Player

Yes that looks almost good (I think). However, the first line puzzles me a bit 0 => 0.997972 0.0020284(flush) 0 (I was also wrong in my previous post) With an empty pit, the only thing that can happen is that freedepth decreases so + 0 - 0 => 1 0 0 With a pit that has only \"blue\" blocks,...

Re:BL2 Bot Player

I am sorry, I probably wasn\'t clear enough. What I really want would to be these probabilities, but than as a function of depth. (so as a table) So for instance, at freedepth=4: what are the probabilities that the next move freedepth is >2, is =2 or is <2. So per depth, 3 probabilities. The values ...

Re:BL2 Bot Player

Ok I thought a bit about the statistics problem and how to speed up calculation of the average The idea of random walk might actually be very fruitful: Currently, all what we keep from one game is one number. Although one game gives a lot more information! Jean-Luc, would you mind doing a little tes...

Re:BL2 Bot Player

Thanks for the quick answer, yes I forgot to include BotplayerAI. The code looks impressive and it will take me some time to understand. You asked: It would be great and I would really appreciate if you can spend a bit of your time on the stats problems. I had a look at the cumulative distribution, ...

Re:BL2 Bot Player

I am impressed! If you have time, could you run it on 3x3x6 flat? Perhaps, it should be possible to play infinite in this mode. Otherwise definitely in 3x3x7 or 3x3x8. I remember I was quite disappointed how poor my evaluation did in these modes.
