Yes, I will update CPW with them. Some information verifies previous ones and some will wait to be verified in the future. That is why I need clear sources of previous data.Sapling wrote: ↑Sun Feb 09, 2025 9:53 amIf you're interested in adding more information to the table I've filled out full statistics to startpos perft(11) and i'm currently 20% into perft(12).phhnguyen wrote: ↑Sun Feb 09, 2025 8:22 am
Clearly, the information in CPW was not updated from that page. CPW has some extra information such as Captures, E.p., Castles, Promotions which are not on the page.
This information was updated by Alessandro Iavicoli without pointing to the source. Perhaps, it is from his own information. If you know the source, I will update CPW.
That is a problem for CPW editors: how can we update them?Sapling wrote: ↑Sun Feb 09, 2025 9:53 am Either way I do think there should be a note as to what the checks / double checks / discovery checks are actually counting in the CPW table as after perft(7) people get the wrong results because they are counting differently, even though their engine is generating moves correctly.
BTW, what do you mean by "wrong" with "counting differently"? Wrong method or bug in coding? How do you know? Compare to what? Any third source data?
The information about checks, double checks... are extra ones for Perfts. They are fun and may be useful for someone. It is easy to remove them but not fun, IMHO!
IMO, extra information and/or too-depth Perft for Kiwipete positions or any non-starting ones are not useful since Perfts of them are for debugging purposes only. Of course, you could do what you want and someone may find them useful later!
