Circle packing equation
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 … 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 is generally not optimal for small numbers of circles. Specific problems of this … See more Quadrature amplitude modulation is based on packing circles into circles within a phase-amplitude space. A modem transmits data as a series of points in a two-dimensional phase-amplitude plane. The spacing between the points determines the noise tolerance … See more At the other extreme, Böröczky demonstrated that arbitrarily low density arrangements of rigidly packed circles exist. There are eleven circle packings based on the eleven uniform tilings of the plane. In these packings, … See more A related problem is to determine the lowest-energy arrangement of identically interacting points that are constrained to lie within a given surface. The Thomson problem deals … See more There are also a range of problems which permit the sizes of the circles to be non-uniform. One such extension is to find the maximum possible density of a system with two specific … See more • Apollonian gasket • Circle packing in a rectangle • Circle packing in a square • Circle packing in a circle • Inversive distance See more WebPacking circles in a circle - closely related to spreading points in a unit circle with the objective of finding the greatest minimal separation, dn, between points. Optimal solutions have been proven for n ≤ 13, and n = 19.
