Two for One: Tight Approximation of 2D Bin Packing
Abstract In this paper we study the two-dimensional geometrical packing problem (2DBP): given a list of rectangles provide a packing all these into the smallest possible number of 1×1 bins without rotating the rectangles We present a -approximate algorithm which improves over the |
What is two dimensional bin packing problem (2d-bpp)?
The two-dimensional bin packing problem (2D-BPP) consists of packing without overlap, a set I of two-dimensional rectangular items into the minimum number of two-dimensional rectangular bins [ 1 – 3 ]. All the bins are identical with width W and height H, and each item i ∈ I has a specific width w and height h.
What are bin packing problems?
Bin packing problems are similar to cutting stock problems [ 13 ]. Indeed, in the bin packing problems, the item set is strongly heterogeneous, that is, there are many types of elements with small demand for each one. In the worst case, all the items have different sizes and demands equal to one.

What are heuristic approaches to bin packing?
It is common that heuristic approaches for the bin packing problem present at least two phases: first, the selection of the next piece to be placed and the cor-responding object to place it; and second, the actual placement of the selected piece in a position inside the object according to some given criteria.

The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins used.- The best existing algorithm for optimal bin packing is due to Martello and Toth (Martello & Toth 1990a; 1990b). We present a new algorithm for optimal bin packing, which we call bin completion, that explores a different problem space, and appears to be asymptotically faster than the Martello and Toth algorithm.
