Mashruuca Stockfish, oo lagu qaybiyay shatiga GPLv3, ayaa dacweeyay ChessBase, iyada oo la noqotay shatiga GPL si ay u isticmaasho koodka. Stockfish waa mashiinka chess ee ugu xoogan ee loo isticmaalo adeegyada chess lichess.org iyo chess.com. Dacwada waxaa la gudbiyay iyadoo ay ugu wacan tahay ku darida koodka Stockfish ee alaabta la iska leeyahay iyada oo aan la furin koodhka isha shaqada.
ChessBase waxay caan ku ahayd barnaamijkeeda chess ee Fritz ilaa 1990-meeyadii. 2019, waxay sii daysay mishiinka Fat Fritz, oo ku salaysan shabakada neerfaha ee isha furan ee Leela Chess Zero engine, kaas oo hal mar ku salaysnaa horumarka mashruuca AlphaZero ee Google furay. Tani ma ahayn xadgudub sharci kasta, in kasta oo horumarinta Leela aysan ku faraxsanayn in ChessBase ay u dhigtay Fat Fritz horumar madaxbannaan, iyada oo aan la aqoonsan mudnaanta kooxaha AlphaZero iyo LeelaZero.
2020, ChessBase waxa ay sii daysay Fat Fritz 2.0, oo ku salaysan matoorka Stockfish 12, kaas oo leh qaab dhismeedka shabakada neerfaha NNUE (ΖUIN, Shabakadaha Neerfaha ee Waxtarka La cusboonaysiin karo). Kooxda Stockfish, oo kaashanaya qareeno, waxay awoodeen inay helaan DVD-ga barnaamijka Fat Fritz 2.0 ee Jarmalka oo laga saaray silsiladaha tafaariiqda, laakiin, kuma qanacsanayn natiijada, waxay ku dhawaaqeen ka noqoshada shatiga GPL ee Stockfish ee ChessBase, iyo ayaa dacwad ka gudbiyay.
Tani ma aha xilli ciyaareedkii ugu horreeyay ee riwaayadaha ku xeeran xeerka Stockfish, oo matoorada ganacsigu ay amaahdaan iyagoo iska indha tiraya GPL. Tusaale ahaan, horraantii waxaa jirtay dhacdo la socota qulqulka koodhka isha ee mashiinka Houdini 6, kaas oo ay caddaatay in ay ku salaysan tahay code Stockfish. Houdini 5 wuxuu ku tartamay tartanka TCEC wuxuuna ka dhigay Xiliga 2017 Grand Final, laakiin ugu dambeyntii waxaa ku guuldareystay Stockfish. 6, nooca xiga ee Houdini 2020 wuxuu awooday inuu ku guuleysto TCEC Season XNUMX Grand Final ka dhanka ah Komodo. Koodhka isha, oo la sii daayay XNUMX, ayaa shaaca ka qaaday khiyaanadan aan quduuska ahayn ee ku xad gudubta mid ka mid ah rukunnada FOSS - GPL.
Aynu dib u xasuusanno in shatiga GPL uu siinaya suurtagalnimada in lagala noqdo shatiga ku xad-gudbiyaasha iyo joojinta dhammaan xuquuqaha shatiga uu ku siiyay shatigan. Iyadoo la raacayo qawaaniinta joojinta shatiga ee lagu ansixiyay GPLv3, haddii xadgudubyada la aqoonsaday markii ugu horeysay oo la tirtiro 30 maalmood gudahood laga bilaabo taariikhda ogeysiinta, xuquuqda shatiga waa la soo celinayaa oo shatiga si buuxda lama burin (heshiisku wuu jiraa) . Xuquuqda isla markiiba sidoo kale waa la soo celiyaa haddii ay dhacdo in la tirtiro xadgudubyada, haddii qofka haysta xuquuqda daabacaadda uusan ogeysiin xadgudubka 60 maalmood gudahood. Haddii waqtiyada kama dambaysta ah ay dhaceen, markaa jebinta shatiga waxaa loo tarjumi karaa xadgudub ku ah heshiiska, kaas oo ganaax lacageed laga heli karo maxkamadda.
