WebDec 9, 2011 · The Finite-circle Method (FCM) is further developed to solve 2D and 3D packing optimization problems with system compactness and moment of inertia constraints here. Instead of using the real geometrical shape as in existing solutions, we approximate the components and the design domain with circles of variant radii. Such approximation … WebJan 8, 2024 · 1 Answer Sorted by: 4 Try these two non-equivalent optimal packings of 4 circles in an L-shaped region. 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.

Dense packings of congruent circles in a circle
WebDec 3, 2024 · Consider the following diagram of a triangular packing: If the circles have radius r, then each pair of horizontal red lines is a distance r apart, and they're a distance r from the edges. Each pair of vertical blue … WebA simple packing of a collection of rectangles contained in [ 0, 1](2) is a disjoint subcollection such that each vertical line meets at most one rectangle of the packing.

Circle packing - Wikipedia
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. One such extension is to find the maximum possible … See more • Apollonian gasket • Circle packing in a rectangle • Circle packing in a square • Circle packing in a circle • Inversive distance 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 with the lowest energy distribution of identical electric charges on the surface of a … 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 … See more WebAn optimal solution of the circle packing problem is determined by an optimal solution of the point packing problem, and vice versa. 2 Mih´aly Csaba Mark´ot, Tibor Csendes Formally, we are looking for all optimal solutions of maximize min 1≤i6= j≤n (x i −x j) 2 +(y i −y j) 2, (1) Weboptimized is the density of a packing, which is the area occupied by the circles of the packing divided by the area of the larger, enclosing circle.
