在歐洲圍棋大會,樊麾老師談到了AlphaGo對大雪崩定式的看法。AlphaGo對妖刀定式
又有什麼看法呢?

圖1就是妖刀定式的基本型。在Master與職業棋士的對局中出現過圖2的變化:

AlphaGo認為白4靠不好,至黑19拆邊,白棋的勝率下降近15個百分點。

圖3是AlphaGo所認為的雙方最佳下法。如果圖3中的黑5選擇圖4的擋下,

至白12將形成戰鬥,AlphaGo認為白棋稍微有利。
心得:圖2先輸15%......,圍棋竟然這樣就輸了15%???
AlphaGo真的觀念領先我們太多太多太多了。
PS:我拿RN跑這個變化圖,白棋的價值網路勝率為38.6%,不過怎麼判斷就看大家了。
Aja臉書補充:
圖3的三路跳已經有職業棋手在正式比賽中下過(圖5)。

在這個局部,AlphaGo的下法(白1至11)與黨毅飛九段是一致的,並且AlphaGo認為全局
仍然是雙方均勢。
