When is it possible to pack the sets X 1, X 2,… into a given “container” X? This is the typical form of a packing problem; we seek conditions on the sets such that disjoint congruent copies (or perhaps translates) of the X. Contrary to what you might expect, this article is not actually about sausages. An arrangement in which the midpoint of all the spheres lie on a single straight line is called a sausage packing, as the convex hull has a sausage-like shape. 1 [[quoteright:350:2 [[caption-width-right:350:It's pretty much Cookie Clicker, but with paperclips. 8.

IfQ has minimali-dimensional projection, 1≤i<d then we prove thatQ is approximately a sphere. A. The first among them. For polygons, circles, or other objects bounded by algebraic curves or surfaces it can be argued that packing problems are computable. Fejes Toth conjectured that in Ed, d ≥ 5, the sausage arrangement is denser than any other packing of n unit balls. Radii and the Sausage Conjecture. From the 42-dimensional space onwards, the sausage is always the closest arrangement, and the sausage disaster does not occur. The work stimulated by the sausage conjecture (for the work up to 1993 cf. Introduction. The critical parameter depends on the dimension and on the number of spheres, so if the parameter % is xed then abrupt changes of the shape of the optimal packings (sausage catastrophe. 3 Optimal packing.
