Optimal circle packing

WebApr 10, 2024 · The one-dimensional circle packing problem is as follows. You have N circles of radius r 1, r 2, ..., rn. These circles are packed in a box such that each circle is tangent to the bottom of the box, and are arranged in the original order. The problem is to find the order of circles that will lead to the optimal (minimum) width of the minimum ...
