Crafty Play By Elo ( Crafty v25.3)
Post by MikeB » Mon Jan 23, 2017 2:48 am

"The Crafty team is pleased to announce the release of Crafty 25.3 with the addition of a Play of ELO feature - this is strictly a chess players version as there are no other changes to the code. You may also download the Crafty Chess Informant opening books, based on the games published over the last 50 years by Chess Informant. Just include them in the directory where you place the Crafty exe and crafty wil access them automatically.

Will add windows and linux versions as they become available."

" Crafty 25.3 features playing strength adjustment between 800 and 2600 Elo"


http://kingqueenofchess.forumotion.com/ ... afty-v25-3

A non busy "sleep" for the appropriate time for the time control selected is enabled by default so it will not play instantaneously. Selecting a rating below 1200 enables skill level which will slowly degrade the skill level the more one selects a rating below 1200. A rating between 1200 and 2600 uses Crafty full evaluation function with no deliberate evaluation weakening, it simply reduces the number of nodes searched. Every increase of 100 ELO points will double the number of nodes searched on average. There is also built-randomization factor that varies the number of nodes on any given move to increase variability in play.

My Understanding based on The post is That Crafty 25.3 (Play By ELO) was already released quite A while back...how do we separate this "New Crafty v25.3 from The Old Crafty 25.3 (Elo)...Looks to create some sort of problem..Let us all know
Thx AR.

Ignore Crafty 25.3 from 2017 - that was an unofficial release that only add play by elo functionality over 25.2. The more recent 25.3 corrected bugs and added 7 man syzygy support. I should have named the 25.3 from 2017 something else. Going forward, play by elo will be a separate branch. My bad.

Well Thats all good but the whole world has tested that "old 25.3 and posted the results" how do we differentiate the New 25.3 from the Old 25.3?... Is the one from 2017-2018 Version 1 and is the 2019 engine version 2? Otherwise there is bound to be some confusion....Thx AR

sorry if you're confused , but you're are talking about releases two years apart - please show me where it matters on some 3rd party website.
