Aaah good old times.
Since it's pretty quiet on the forum, I thought I'd find us all a nice riddle.
I was cruising through the pile of easier ones when I found this one.
Still haven't found the answer
A warden meets with 23 prisoners. He tells them the following:
What initial strategy is 100% guaranteed to let all go free?
(originally from http://mathriddles.williams.edu/?p=146&cpage=1#comments )
All right, I got very close to the answer, but was stuck with the condition that their positions were unknown. Was too impatient and googled it (shame on me). If you think you have the answer, pm me :). If you want to discuss the riddle, use this thread.
