"Be the change you want to see in the world" - Gandhi 

This weeks maths problem:

Find the maximum number (N) of discs diameter (D) from rectangular plate (X by Y).

 

What assumptions have you made about the spacing between the discs and the discs and the edges?

This is a real world problem from the steel industry. The solution is surprisingly non-linear and non-regular packing is sometimes the optimum solution.
