Parallel greedy algorithms for packing unequal spheres into a cuboidal strip or a cuboid

Kubach, Timo; Bortfeldt, Andreas; Tilli, Thomas; … - Fernuniversität <Hagen> / Fachbereich … - 2009

Given a finite set of spheres of different sizes we study the three-dimensional StripPacking Problem (3D-SPP) as well as the three-dimensional Knapsack Problem (3D-KP).The 3D-SPP asks for a placement of all spheres within a cuboidal strip of fixed width andheight so that the variable length of...
