WebPacking problems are a class of optimization problems in mathematics that involve attempting to pack objects together into containers. The goal is to either pack a single container as densely as possible or pack all objects using as few containers as possible. WebCircle Packing The simplest version of the problem is the reduction to two dimensions, where the goal is to tile the plane with circles in the such a way that maximizes density. A very natural approach is to arrange the circles in a hexagonal pattern, as shown: optic basketball box

WebThis honeycomb forms a circle packing, with circles centered on each hexagon. The honeycomb conjecture states that a regular hexagonal grid or honeycomb has the least total perimeter of any subdivision of the plane into regions of equal area. The conjecture was proven in 1999 by mathematician Thomas C. Hales. [1] Theorem [ edit] WebAlso known as a Circular Treemap .
