M313: Exciting math puzzles (and their exciting math)! in Splash Spring 18 (Mar. 04, 2018)
Suppose we give three people black and white hats by tossing a fair coin; then we ask individually what their hat color is. They can either guess it or pass. Now, how can you maximize your chances that one person gets the correct answer if we need to make sure that noone is wrong? One caveat: noone hears the other peoples' answer. What if we had 7 people? 255?
How about the following: 10 people are lined up tallest the shortest on a line, and we ask from back to front what their hat color is; how can you ensure that at most one person gets their hat color correctly? What if we had 100 people? 1000?
Maybe this puzzle? We have n people, and m possible colors for hats, and m < n; how can you make sure that at least one person guesses their hat color correctly?
There are loads more puzzles (Alice and Bob are sending a suitcase to each other with padlocks; 100 prisoners in a room opening 50 boxes to find their number; the classic blue eyesgreen eyes puzzle; the checkerboard puzzle; the last card trick of the game of SET), and each of these relies on various interesting branches of mathematics and computer science! (Abstract algebra, combinatorics, algorithms, information theory, probability, logic, random graph theory etc.) While we cannot hope to explore all of these puzzles to a sufficient depth (and the associated mathematical fields) in an hour, we can do a few of these to get a taste of some of the puzzles!
