WebNov 12, 2012 · Packing efficiency The algorithm works quite poorly on identically-sized circles (it cannot find the famous honeycomb pattern for 20 circles in a square), but pretty well on a wide distribution of random radii. Aesthetics The result is pretty ungainly for identical-sized circles. WebDec 1, 2004 · A new interval branch-and-bound algorithm designed specifically for this optimization problem of finding the densest packings of non-overlapping equal circles within a unit square is introduced. The paper deals with the problem class of finding the densest packings of non-overlapping equal circles within a unit square. We introduce a new …
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 ... In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the … See more In the two-dimensional Euclidean plane, Joseph Louis Lagrange proved in 1773 that the highest-density lattice packing of circles is the hexagonal packing arrangement, in which the centres of the circles are arranged … See more Packing circles in simple bounded shapes is a common type of problem in recreational mathematics. The influence of the container walls is important, and hexagonal packing … See more There are also a range of problems which permit the sizes of the circles to be non-uniform.

You can put in small indentations to prevent "rattlers" from rattling, or instead of the L take the "shape" to be the union of the circles. EDIT: Here's an example where the shape is convex.
