A REVISIT TO THE EIGHT COINS PROBLEM

摘要

The eight coins problem is a well-known problem in mathematics as well as in computer science. In this problem eight coins are given of which only one is false, either heavier or lighter. The objective is to find out the false coin using a minimum number of comparisons amongst the coins; and also to determine the characteristic feature of the false coin whether it is heavier or lighter in comparison to each of the true coins.
