# The Tiffany Problem: A Deeper Dive

Have you ever wondered why the Tiffany Problem is so important? In this blog post, we will take a deeper dive into the Tiffany Problem and explore its significance in the field of mathematics. We will also discuss some of the different approaches that have been used to solve the problem and the challenges that still remain.

## What is the Tiffany Problem?

The Tiffany Problem is a mathematical problem that asks for the maximum number of non-overlapping squares that can be placed on a chessboard. The problem is named after Lewis Carroll, who first posed it in 1879. Carroll was inspired by the stained glass windows of Tiffany & Co., which often featured intricate patterns of squares.

The Tiffany Problem is a challenging problem to solve, and it has attracted the attention of mathematicians for over a century. In 1910, the mathematician Max Dehn proved that the maximum number of non-overlapping squares that can be placed on a chessboard is 31. This result was later improved by other mathematicians, and the current best known upper bound is 35.

## Approaches to Solving the Tiffany Problem

There are a number of different approaches that have been used to solve the Tiffany Problem. One approach is to use a brute-force search algorithm to try all possible arrangements of squares on the chessboard. This approach is guaranteed to find the maximum number of squares, but it is very inefficient. Another approach is to use a divide-and-conquer algorithm to break the problem down into smaller subproblems. This approach is more efficient than a brute-force search, but it can still be very time-consuming.

A third approach to solving the Tiffany Problem is to use a mathematical technique called linear programming. Linear programming can be used to find the maximum number of squares that can be placed on a chessboard subject to certain constraints. This approach is often used in conjunction with other approaches to solve the problem.

## Challenges and Open Questions

Despite the progress that has been made in solving the Tiffany Problem, there are still a number of challenges and open questions that remain. One challenge is to find a more efficient algorithm for solving the problem. The current best known algorithm has a time complexity of O(n^6), where n is the size of the chessboard. This means that the algorithm takes a very long time to run for large chessboards.

Another challenge is to find a way to prove that the current best known upper bound of 35 is the maximum number of non-overlapping squares that can be placed on a chessboard. This is a very difficult problem, and it is not clear how to approach it.

## Conclusion

The Tiffany Problem is a challenging and fascinating mathematical problem that has attracted the attention of mathematicians for over a century. While some progress has been made in solving the problem, there are still a number of challenges and open questions that remain. The Tiffany Problem is a reminder that there are still many unsolved problems in mathematics, and that there is still much to learn about the world around us.
