In this web site there are the solutions of a lot of packing squares problems. I know a very simple method to calculate with pen and paper the solution for the ten squares in a square using the same method than for five squares.
But now I try the eleven squares and the problem seems to be difficult, I try some approximations but they were not very conclusive. So I made a "puzzle" with eleven piece of paper and tried some configurations but they were not really interesting.
So I searched online but I find nothing about Walter Trump's method and I don't want to buy a book for $40 just to know the solution.
Have you got some ideas which can help me ?
Thank you in advance
