EP-P109-邏輯推理遊戲：真假亂答－三問辨識三仙派

EP-P109-邏輯推理遊戲：真假亂答－三問辨識三仙派 　　本集邏輯推理遊戲「真假亂答－三問辨識三仙派」，題目如下所述： 　　雲隱山深處，相傳住著三個神祕仙門。凡人若能拜入正確仙門，便有機會修得不死仙道；若拜錯門派，恐將永困山中。少年修道者沈雲澈歷經艱險，終於來到雲霧繚繞的「三清石門」前。　　門前坐著玄曜、清衡、無塵三位仙人，分別來自三個仙門：　•太真閣：門人言出必真。　•幻妄門：門人語語皆假。　•無定觀：門人回答真偽無常，全憑當下心情，無法預測。　　沈雲澈必須先確認三位仙人各屬哪一派，才能決定拜入何門。然而，考驗極其嚴苛：三位仙人都聽得懂凡語，但只會使用仙界古語中的兩個字回答：「達」與「伽」。這兩個字一個代表「是」，一個代表「否」，但沒人知道哪一個才是「是」。考驗規則：　1.沈雲澈總共只能問三個「是或否」的問題。　2.每一個問題只能問其中一位仙人，但他可以對同一位仙人提問多次。　3.目標是精準指出三位仙人的所屬門派。 　　您的挑戰：如果您是沈雲澈，該如何設計這三個問題，在您聽不懂仙人回答，且有仙人隨機亂答的情況下，百分之百破解他們的身分？ 　　註：本集系改編自《最難的邏輯謎題》，是由美國哲學家和邏輯學家喬治．鮑洛斯（George Boolos）於1996年發表在《哈佛哲學評論》上的邏輯謎題。　　Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes–no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for yes and no are da and ja, in some order. You do not know which word means which.　　Boolos provides the following clarifications: a single god may be asked more than one question, questions are permitted to depend on the answers to earlier questions, and the nature of Random's response should be thought of as depending on the flip of a fair coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely. 　　答案及詳細解說，將於「亞瑟邏輯學堂」FB粉絲專頁公開。請點選說明或逐字稿中連結觀看。 解說 EP-P109-邏輯推理遊戲：真假亂答－三問辨識三仙派https://www.facebook.com/share/p/16zK5YP6rL/ 「亞瑟邏輯學堂」FB粉絲專頁https://www.facebook.com/arthurlogic 　　我們的節目內容在各大Podcast、YouTube同步上架，請搜尋「亞瑟邏輯學堂」。謝謝收聽！歡迎下次再來到「亞瑟邏輯學堂」。留言告訴我你對這一集的想法： https://open.firstory.me/user/cluwlhkv70k2a01ujea7nanlc/commentsMail：[email protected] Powered by Firstory Hosting
