4 unknown coins - another weighing puzzle
Posted 27 November 2012 - 08:39 PM
Goal: You need to organize the coins based on their relative weight, i.e. sort them by weight grouping identical coins together. All you have is a balance scale that tells you which side of the scale is heavier or if the sides are in balance.
Question 1: What's the minimum number of weighings required to achieve the goal?
Question 2: Provide a method that accomplishes the goal in the minimum number of weighings.

Is that sort of what you mean?
(What an interesting weighing puzzle!)

This is the same solution that I've found to be the best so far. Now, I've been trying to either find a way to do it in 4 weighings or prove that it cannot be done.
