Proiectul Stockfish, distribuit sub licen\u021ba GPLv3, a dat \u00een judecat\u0103 compania ChessBase, retr\u0103g\u00e2ndu-i licen\u021ba GPL pentru utilizarea codului s\u0103u. Stockfish este cel mai puternic dintre motoarele de \u0219ah folosite pe serviciile de \u0219ah lichess.org \u0219i chess.com. Procesul a fost intentat din cauza includerii codului Stockfish \u00eentr-un produs proprietar f\u0103r\u0103 a deschide codul surs\u0103 al lucr\u0103rii derivate. <\/p>\n
Compania ChessBase este cunoscut\u0103 pentru programul s\u0103u de \u0219ah Fritz \u00eenc\u0103 din anii 1990. \u00cen 2019, aceasta a lansat motorul Fat Fritz, bazat pe re\u021beaua neuronal\u0103 a motorului open-source Leela Chess Zero, care, la vremea sa, s-a bazat pe realiz\u0103rile proiectului AlphaZero, deschis de Google. Aceasta nu a constituit o \u00eenc\u0103lcare a legisla\u021biei, de\u0219i dezvoltatorii Leela au fost nemul\u021bumi\u021bi c\u0103 ChessBase a pozi\u021bionat Fat Fritz ca o dezvoltare independent\u0103, f\u0103r\u0103 a recunoa\u0219te meritele echipelor AlphaZero \u0219i LeelaZero. <\/p>\n
\u00cen 2020, compania ChessBase a lansat produsul Fat Fritz 2.0, bazat pe motorul Stockfish 12, care are propria arhitectur\u0103 de re\u021bea neuronal\u0103 NNUE (ƎU\u0418\u0418, Re\u021bele Neuronale Eficient Actualizabile). Echipa Stockfish, cu ajutorul avoca\u021bilor, a reu\u0219it s\u0103 ob\u021bin\u0103 retragerea din re\u021belele comerciale DVD a programului Fat Fritz 2.0 \u00een Germania, dar, nesatisf\u0103cut\u0103 de rezultat, a declarat despre retragerea licen\u021bei GPL pentru Stockfish de la ChessBase \u0219i a intentat un proces \u00een instan\u021b\u0103. <\/p>\n
Aceasta nu este prima sezon de dram\u0103 \u00een jurul codului Stockfish, pe care motoarele comerciale \u00eel \u00eemprumut\u0103 ignor\u00e2nd GPL. De exemplu, anterior a avut loc un incident cu scurgerea codului surs\u0103 al motorului proprietar Houdini 6, din care a reie\u0219it c\u0103 se bazeaz\u0103 pe codul Stockfish. Houdini 5 a participat la competi\u021bia TCEC \u0219i a ajuns \u00een superfinala sezonului nou\u0103, dar \u00een cele din urm\u0103 a cedat \u00een fa\u021ba Stockfish. \u00cen 2017, urm\u0103toarea versiune Houdini 6 a reu\u0219it s\u0103 \u00eenving\u0103 Komodo \u00een superfinala TCEC a sezonului zece. Codul surs\u0103, scurs \u00een 2020, a dezv\u0103luit aceast\u0103 \u00een\u0219el\u0103torie nelegitim\u0103, care \u00eencalc\u0103 unul dintre pietrele de temelie ale FOSS — GPL. <\/p>\n
Amintim c\u0103 licen\u021ba GPL prevede posibilitatea revoc\u0103rii licen\u021bei \u00een cazul \u00eenc\u0103lc\u0103rii \u0219i \u00eencet\u0103rii tuturor drepturilor licen\u021biatului acordate prin aceast\u0103 licen\u021b\u0103. Conform regulilor de reziliere adoptate \u00een GPLv3, dac\u0103 \u00eenc\u0103lc\u0103rile au fost identificate pentru prima dat\u0103 \u0219i corectate \u00een termen de 30 de zile de la notificare, drepturile asupra licen\u021bei sunt restabilite, iar licen\u021ba nu este complet revocat\u0103 (contractul r\u0103m\u00e2ne valabil). Drepturile sunt, de asemenea, restituite imediat \u00een cazul remedierii \u00eenc\u0103lc\u0103rilor, dac\u0103 titularul drepturilor nu a notificat despre \u00eenc\u0103lcare \u00een termen de 60 de zile. Dac\u0103 termenul a expirat, atunci \u00eenc\u0103lcarea licen\u021bei poate fi interpretat\u0103 ca o \u00eenc\u0103lcare a contractului, pentru care se pot solicita desp\u0103gubiri financiare \u00een instan\u021b\u0103. \u041f\u0440\u043e\u0435\u043a\u0442 Stockfish, \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u043c\u044b\u0439 \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u0435\u0439 GPLv3, \u043f\u043e\u0434\u0430\u043b \u0432 \u0441\u0443\u0434 \u043d\u0430 \u043a\u043e\u043c\u043f\u0430\u043d\u0438\u044e ChessBase, \u043e\u0442\u043e\u0437\u0432\u0430\u0432 \u0443 \u0442\u043e\u0439 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u044e GPL \u043d\u0430 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435 \u0441\u0432\u043e\u0435\u0433\u043e \u043a\u043e\u0434\u0430.
