Introduction (last change: 2020-12-08)
10
The new RWBC XB/UCI Chronology is based on the WB/UCI chronology pages, which I started in July 2002 and were updated last time at the end of 2010.
11
At that time I finally lost my interest in computerchess due to all the cloning issues and useless nearly unchanged derivates of already available sources.
12
However after a long hiatus I decided to create an updated chronology again.
13
14
After some pondering about how to shrink the dark aspects caused by the desire of some people to release chess programs at all costs, I decided to
15
follow a set of semi-strict rules with hopefully clear conditions.
16
(1) No clones, no closed source attempts of available open source projects
17
(2) No 'stupid' derivates (source code available, but unchanged, or tiny changes and origin not openly acknowledged from start)
18
(3) Not even legal derivates, when there isn't much code changed and own ideas aren't added over a longer period and move selection/search is too similar to origin
19
(4) In case of doubts (mine and others), or if it concerns probably only some versions of a program, those programs are marked (s. appendix)
20
(5) Versions of programs, which are definitely proven to be against this standard are omitted and the associated column is also marked (s. appendix)
21
(6) Programs of anonymous origin also won't be added, except EasyPeasy, an engine coming with the free Mayura Chess GUI
22
(7) No programs from unknown authors w/o source , who cannot be verified and have no website, but instead use anonymous download sites
23
(8) No intentionally created 'random' or 'pseudo random' movers
24
(9) No too buggy programs (at least after 2019 - for previous periods I cannot change history)
25
26
The update frequency is planned to be around 2 times per month. In case of several important releases soon after an update I might add those
27
directly into the released (copy) spreadsheet(s) and add the changes later to the private (master) spreadsheet(s).
28
29
If you miss a certain program or a version here, most probably one of the reasons is mentioned above. In this case a good start would be to check the
30
clone list at the wonderful ComputerChessWiki: http://computer-chess.org/doku.php?id=computer_chess:wiki:lists:clone_engine_list
31
or the complete release list at the same place: http://computer-chess.org/doku.php?id=computer_chess:wiki:lists:chess_engine_list
32
33
Because of the huge amount of data and for other reasons there is no guarantee everything is correct! Especially the release date sometimes can be the
34
date of discovery (mostly if only the source was available) or the date of compilation by another person.
35
Please inform me about obvious errors either via mail to rwbc[at]gmx.de or to the Talkchess CCC forum. (You need to prove your data)
