Sphere Packings for Arbitrary Objects SpringerLink
The sphere packing problem is the three-dimensional version of a class of ball-packing problems in arbitrary dimensions. In two dimensions, the equivalent problem is packing circles on a plane. In one dimension it is packing line segments into a linear universe. In dimensions higher than three, the densest … See more In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. … See more Dense packing In three-dimensional Euclidean space, the densest packing of equal spheres is achieved by a family … See more Many problems in the chemical and physical sciences can be related to packing problems where more than one size of sphere is … See more The contact graph of an arbitrary finite packing of unit balls is the graph whose vertices correspond to the packing elements and whose two vertices are connected by an … See more A lattice arrangement (commonly called a regular arrangement) is one in which the centers of the spheres form a very symmetric pattern which needs only n vectors to be … See more If we attempt to build a densely packed collection of spheres, we will be tempted to always place the next sphere in a hollow between three … See more Although the concept of circles and spheres can be extended to hyperbolic space, finding the densest packing becomes much more difficult. In a hyperbolic space there is no limit to the number of spheres that can surround another sphere (for … See more WebAug 6, 2024 · So a solution for packing identical spheres into a unit sphere can easily be transformed to a solution to your problem. Proven optimal solutions for packing identical spheres into a sphere only exist up to n=12. So I guess you will also have to live with near-optimal solutions, at least for n>12. pottery barn discount codes coupons
