WebThe circle packing problem is a well studied problem [12] whose aim is the packing of a certain number of circles, each one with a fixed known radius (not necessary the same for each circle) inside a container. The shape of the container may vary from a circle, a square, a rectangular, etc. WebFeb 26, 2024 · These packings have been generated by taking the hex number packings (see above) as templates and scratching a straight row of circles from one of the vertices of the hexagon to its opposite vertex, inclusive. So we have N = Hk -2 k +1. Finally, the whole packing is slightly expanded in their radii until all circles jam.
