I haven't played 20 questions recently, but in response to your comment I just went to www.20q.net and played thinking of Alice in Wonderland, the book. The neural net guessed "is it a novel" on question 22, and then decided it had gone far enough and said "you won, but 20q guessed it eventually". However, I have distinct recollections of, last time I played, a human player guessing my thought of a specific radio station. Of course, 20q.net cheats by asking multimodal questions (animal,vegetable, or mineral) so more than 2^20 possibilities. ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
