Iphrojekthi ye-Stockfish, esatshalaliswa ngaphansi kwelayisensi ye-GPLv3, yamangalela i-ChessBase, ihoxisa ilayisensi yayo ye-GPL yokusebenzisa ikhodi yayo. I-Stockfish iyinjini ye-chess enamandla kunazo zonke esetshenziswa kumasevisi we-chess lichess.org kanye ne-chess.com. Icala lifakwe ngenxa yokufakwa kwekhodi ye-Stockfish kumkhiqizo wobunikazi ngaphandle kokuvula ikhodi yomthombo yomsebenzi osuselwe.
I-ChessBase yaziwa ngohlelo lwayo lwe-Fritz chess kusukela ngawo-1990. Ngo-2019, yakhipha injini ye-Fat Fritz, esekelwe kunethiwekhi ye-neural yenjini evulekile ye-Leela Chess Zero, eyayisekelwe ekuthuthukisweni kwephrojekthi ye-AlphaZero evulwe yi-Google. Lokhu bekungekona ukwephulwa kwanoma yimuphi umthetho, nakuba abathuthukisi be-Leela bebengajabule ngokuthi i-ChessBase ibeke u-Fat Fritz njengentuthuko ezimele, ngaphandle kokubona ukufaneleka kwamaqembu e-AlphaZero ne-LeelaZero.
Ngo-2020, i-ChessBase yakhipha i-Fat Fritz 2.0, esekelwe enjinini ye-Stockfish 12, ene-neural network architecture i-NNE (ΖUIN, Efficiently Updatable Neural Networks). Ithimba le-Stockfish, ngosizo lwabameli, likwazile ukuthola i-DVD ngohlelo lwe-Fat Fritz 2.0 eJalimane lihoxisiwe emaketangeni okuthengisa, kodwa, lingagculisekile ngomphumela, lamemezela ukuhoxiswa kwelayisensi ye-GPL ye-Stockfish e-ChessBase, futhi. wafaka icala.
Lena akuyona isizini yokuqala yedrama ehambisana nekhodi ye-Stockfish, izinjini zezohwebo eziyiboleka kuyilapho ziyiziba i-GPL. Isibonelo, phambilini kube nesigameko sokuvuza kwekhodi yomthombo wenjini ye-Houdini 6, okwavela kuyo ukuthi isekelwe kukhodi ye-Stockfish. UHoudini 5 uqhudelane emqhudelwaneni we-TCEC wafinyelela ku-Season 2017 Grand Final, kodwa wagcina ehlulwe yi-Stockfish. Ngo-6, inguqulo elandelayo ye-Houdini 2020 yakwazi ukunqoba i-TCEC Season XNUMX Grand Final ngokumelene ne-Komodo. Ikhodi yomthombo, eputshuzwe ngo-XNUMX, yembula le nkohliso engengcwele ephula elinye lamatshe ekhona e-FOSS - i-GPL.
Masikhumbule ukuthi ilayisensi ye-GPL inikeza ithuba lokuhoxiswa kwelayisensi yomephula umthetho futhi kunqanyulwe wonke amalungelo omnikazi welayisensi anikezwe yona yile layisensi. Ngokuhambisana nemithetho yokunqanyulwa kwelayisense eyamukelwe ku-GPLv3, uma ukwephulwa komthetho kuhlonzwe okokuqala futhi kwaqedwa phakathi nezinsuku ezingama-30 kusukela osukwini lwesaziso, amalungelo elayisensi ayabuyiselwa futhi nelayisensi ayihoxiswa ngokuphelele (inkontileka ihlala injalo) . Amalungelo abuyiselwa ngokushesha futhi uma kwenzeka kuqedwa ukwephulwa, uma umnikazi we-copyright engazange aziswe ngokwephulwa phakathi kwezinsuku ezingama-60. Uma izikhathi zokugcina seziphelile, khona-ke ukwephulwa kwelayisensi kungahunyushwa njengokuphulwa kwenkontileka, lapho izinhlawulo zezezimali zingatholakala enkantolo.
