TITLE: Generalizations of the Counterfeit Coin Problem
I will be discussing several generalizations (to n weighings) of the following problem:
You have a balance scale and twelve coins. Exactly one of the coins is counterfeit and, therefore either heavier of lighter than a genuine coin, but you do not know which. Using only three weighings, can you identify the counterfeit coin and decide whether it is too heavy or too light?
