'''Ippolit''',<br/>
an [[UCI]] compliant [[:Category:Open Source|open source engine]] by [https://en.wikipedia.org/wiki/Pseudonym pseudonymous] authors. A former '''CPW''' page of ''Ippolit'' by one of its authors from May 2009, was preliminary deleted due to a claim by [[Rybka]] author [[Vasik Rajlich]], '''CPW''' would support [https://en.wikipedia.org/wiki/Software_piracy piracy sites] and who implied ''Ippolit'' is a [[:Category:Clone|clone]] or derivative from ''Rybka 3'' <ref>private communication with [[Gerd Isenberg]]</ref> , apparently due to [http://www.program-transformation.org/Transform/DisAssembly disassembling] and [https://en.wikipedia.org/wiki/Decompiler decompiling].

=Legal Status=
The authors of ''Ippolit'' call themselves [https://en.wikipedia.org/wiki/Comrade Comrades] and keep pseudonymous. Head Comrade is ''Yakov Petrovich Golyadkin'' <ref>[https://en.wikipedia.org/wiki/The_Double:_A_Petersburg_Poem The Double: A Petersburg Poem] a novella written by [https://en.wikipedia.org/wiki/Fyodor_Dostoevsky Fyodor Dostoyevsky]</ref>, Deputy Head Comrade ''Igor Igorovich Igoronov'', Honorary Comrade ''Vladimir Ilyich Lenin'' <ref>[https://en.wikipedia.org/wiki/Vladimir_Lenin Vladimir Lenin from Wikipedia]</ref>, and further ''Roberto Pescatore'', ''Yusuf Ralf Weisskopf'', ''Ivan Skavinsky Skavar'' <ref>[https://en.wikipedia.org/wiki/Abdul_Abulbul_Amir Abdul Abulbul Amir from Wikipedia]</ref>, and ''Decembrists'' <ref>[https://en.wikipedia.org/wiki/IPPOLIT IPPOLIT from Wikipedia]</ref> <ref>[https://en.wikipedia.org/wiki/Decembrist_revolt Decembrist revolt from Wikipedia]</ref> <ref>[http://users.telenet.be/chesslogik//robbolito.htm ChessLogik - RobboLito] hosted by [[Norman Schmidt]] has a list of [[RobboLito]] comrades and Decembrists</ref>.

Ippolit pages were initially hosted by [https://en.wikipedia.org/wiki/Wikispaces Wikispaces.org]. Ippolit and its successor [[RobboLito]] <ref>[http://users.telenet.be/chesslogik//robbolito.htm ChessLogik - RobboLito] hosted by [[Norman Schmidt]] has a list of RobboLito comrades and Decembrists</ref> were discussed in [[Computer Chess Forums]] from mid October 2009 <ref>[http://www.talkchess.com/forum/viewtopic.php?t=30192 New engine: Ippolit] by [[Vladimir Medvedev]], [[CCC]], October 18, 2009</ref> <ref>[http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=12995 Official statement on [Deleted]?] by [[Vasik Rajlich]], [[Computer Chess Forums|Rybka Forum]], October 21, 2009</ref>, and it is no longer appropriate to ignore them further. The source code is open and distributed. ''Ippolit'' and ''RobboLito'' are apparently as strong or even stronger than ''Rybka 3'' on a single processor. They are therefor likely to hurt interests of commercial chess program authors and companies as well as hobbyist computer chess programmers with all their original efforts over years, and finally the sportive aspects of computer chess, the competition.

The legal status of ''Ippolit'' and its successors, and despite the [https://en.wikipedia.org/wiki/Socialization socialization] of re-engineered knowledge from commercial engines should be matter of independent scientific research possibly under the aegis of the [[ICGA]].

=Origin=
In June 2010, [[Vasik Rajlich]] made following statement on Rybka and Ippolit, which was published by [[Sven Schüle]] in [[CCC]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=34908 My recent correspondence with Vasik Rajlich] by [[Sven Schüle]], [[CCC]], June 13, 2010</ref>:
Ippolit is disassembled Rybka 3 with changes. The changes are considerable but not even close to enough to leave any doubt. Robbolito is an evolved Ippolit, with more changes and more cleanup. I haven't checked the other new engines yet.

The same day [[Zach Wegner]] published a technical summary by former anonymous author "BB+" alias [[Mark Watkins]] about [[Rybka]] and Ippolit <ref>[http://www.open-chess.org/download/file.php?id=13 A comparison of Rybka and IPPOLIT] (pdf)</ref>, which demonstrates differences are substantial <ref>[http://www.open-chess.org/viewtopic.php?f=3&t=119 BB's Rybka/Ippolit comparison] by [[Zach Wegner]], [[Computer Chess Forums|OpenChess Forum]], June 13, 2010</ref>, and he nevertheless concluded he would find it wholly plausible that Ippolit is a "reverse-engineered Rybka with many changes" in the same forum thread. RobboLito's sentinel <ref>[http://users.telenet.be/chesslogik//robbolito.htm ChessLogik - RobboLito] hosted by [[Norman Schmidt]]</ref> [[Milos Stanisavljevic]] <ref>[http://www.rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=15405 Firebird programmers no longer anonymous?] by oudheusa, [[Computer Chess Forums|Rybka Forum]], February 07, 2010</ref> <ref>[http://www.open-chess.org/viewtopic.php?f=3&t=1733#p15264 Re: Is Houdini 2 Legally Copyrighted?] by [[Jeremy Bernstein]], [[Computer Chess Forums|OpenChess Forum]], December 10, 2011</ref> is proponent of Ippolit's originality, despite his note it used ideas from [https://en.wikipedia.org/wiki/Reverse_engineering reverse engineering] [[Rybka|Rybka 3]] <ref>[http://www.talkchess.com/forum/viewtopic.php?topic_view=threads&p=434569&t=41183 Re: WCCC 2011 - Junior is the 2011 World Champion] by [[Milos Stanisavljevic]], [[CCC]], November 25, 2011</ref>.
