<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: I-Passage: Ngo-Okthoba 2015, i-AlphaGo yokuqala yaba uhlelo lokuqala lwe-Go lwekhompyutha ukushaya umdlali we-Go ongumuntu ngaphandle kokukhubazeka ebhodini eligcwele elingu-19 × 19. NgoMashi 2016, yahlula u-Lee Sedol emdlalweni wemidlalo emihlanu, okuyisikhathi sokuqala uhlelo lwe-Go lwekhompyutha selunqobe uchwepheshe we-9-dan ngaphandle kokukhubazeka. Yize yahlulwa nguLee Sedol emdlalweni wesine, uLee wasula emdlalweni wokugcina, wanikeza amaphuzu wokugcina emidlalweni emi-4 kuye ku-1 esivuna i-AlphaGo. Ukuhlonipha ukunqoba, i-AlphaGo yanikezwa i-9-dan yokuhlonipha yiKorea Baduk Association. Ukuhola kanye nomdlalo onzima noLee Sedol kwabhalwa kwifilimu yedokhumenti nayo enesihloko esithi AlphaGo, eqondiswe nguGreg Kohs. Yakhethwa yiSayensi njengomunye wabagijimi be-Breakthrough of the Year ngomhlaka 22 Disemba 2016.Ekuhlanganyeleni kwe-Future of Go Summit ka-2017, owalandela esikhundleni sayo u-AlphaGo Master wanqoba uKe Jie, umdlali obekwe njengo-No.1 emhlabeni ngaleso sikhathi, emdlalweni wemidlalo emithathu i-AlphaGo Zero enamandla kakhulu yayisivele ikhona kodwa yayingakabikwa. Ngemuva kwalokhu, i-AlphaGo yanikezwa i-professional 9-dan yi-Chinese Weiqi Association. I-AlphaGo kanye nabalandeli bayo basebenzisa i-algorithm yokusesha yesihlahla seMonte Carlo ukuthola ukunyakaza kwayo ngokususelwa olwazini obeluvele lufundwe ngokufunda ngomshini, ikakhulukazi ngenethiwekhi ye-neural yokufakelwa indlela yokufunda ejulile ngokuqeqeshwa okubanzi, kokubili kusuka ekudlaleni komuntu nasekhompyutheni. Inethiwekhi yezinzwa iqeqeshelwe ukubikezela ukukhetha kokunyakaza kwe-AlphaGo kanye nemidlalo yomnqobi. Le nethi ye-neural ithuthukisa amandla okucinga esihlahleni, okuholela ekutheni kube nekhwalithi ephakeme yokukhetha ukunyakaza nokudlala okuqinile kokuzilawula ekuphindaphindeni okulandelayo. Umbuzo: Ngasiphi unyaka i-AlphaGo yahlula u-Lee Sadol emdlalweni onemidlalo emihlanu?  <response>: Unyaka wezi-2016
