Ntchito ya Stockfish idasumira ChessBase ndikuchotsa chiphaso cha GPL

Pulojekiti ya Stockfish, yomwe idagawidwa pansi pa layisensi ya GPLv3, idasumira ChessBase, ndikuchotsa chiphaso chake cha GPL kugwiritsa ntchito code yake. Stockfish ndiye injini yamphamvu kwambiri ya chess yomwe imagwiritsidwa ntchito pa chess services lichess.org ndi chess.com. Mlanduwu udaperekedwa chifukwa chophatikizidwa ndi code ya Stockfish m'chinthu chaumwini popanda kutsegula magwero a ntchito yochokera.

ChessBase yadziwika ndi pulogalamu yake ya Fritz chess kuyambira 1990s. Mu 2019, idatulutsa injini ya Fat Fritz, kutengera neural network ya injini yotseguka ya Leela Chess Zero, yomwe nthawi ina idatengera zomwe polojekiti ya AlphaZero idatsegulidwa ndi Google. Uku sikunali kuphwanya malamulo aliwonse, ngakhale opanga Leela sanasangalale kuti ChessBase idayika Fat Fritz ngati chitukuko chodziyimira pawokha, osazindikira kufunikira kwa magulu a AlphaZero ndi LeelaZero.

Mu 2020, ChessBase idatulutsa Fat Fritz 2.0, kutengera injini ya Stockfish 12, yomwe ili ndi ma neural network architecture NNUE (ƎUIN, Efficiently Updatable Neural Networks). Gulu la Stockfish, mothandizidwa ndi maloya, lidatha kutenga DVDyi ndi pulogalamu ya Fat Fritz 2.0 ku Germany yochotsedwa pamaketani ogulitsa, koma, osakhutira ndi zotsatira zake, adalengeza kuchotsedwa kwa chilolezo cha GPL cha Stockfish ku ChessBase, ndi anazenga mlandu.

Ino sinyengo yoyamba ya sewero lozungulira nambala ya Stockfish, yomwe mainjini amalonda amabwereka kwinaku akunyalanyaza GPL. Mwachitsanzo, m'mbuyomu panali chochitika ndi kutayikira kwa code gwero la eni Houdini 6 injini, kumene zinaonekeratu kuti anachokera pa Stockfish code. Houdini 5 adachita nawo mpikisano wa TCEC ndikufika ku Gawo 2017 Grand Final, koma pamapeto pake adataya Stockfish. Mu 6, mtundu wotsatira wa Houdini 2020 udatha kupambana TCEC Season XNUMX Grand Final motsutsana ndi Komodo. Khodi yochokera, yomwe idatsitsidwa mu XNUMX, idawulula chinyengo chopanda chiyero ichi chomwe chimaphwanya imodzi mwamwala wapangodya wa FOSS - GPL.

Tiyeni tikumbukire kuti chilolezo cha GPL chimapereka mwayi wochotsa chilolezo cha wophwanyayo ndikuchotsa ufulu wonse wa chilolezo chomwe wapatsidwa ndi chilolezochi. Mogwirizana ndi malamulo oletsa laisensi omwe adakhazikitsidwa mu GPLv3, ngati zolakwa zidadziwika koyamba ndikuchotsedwa mkati mwa masiku 30 kuchokera tsiku lomwe adadziwitsidwa, ufulu wa chiphasocho umabwezeretsedwa ndipo chilolezocho sichimachotsedwa kwathunthu (mgwirizano umakhalabe) . Ufulu umabwezedwanso nthawi yomweyo ngati kuphwanya kuchotsedwa, ngati mwiniwakeyo sanadziwitse za kuphwanya mkati mwa masiku 60. Ngati nthawi zomalizira zatha, ndiye kuti kuphwanya chilolezo kungatanthauzidwe ngati kuphwanya mgwirizano, zomwe zilango zachuma zingapezeke kukhoti.
