Web2 Bin packing. In the two-dimensional bin packing problem, we are given an unlimited number of finite identical rectangular bins, each having width W and height H, and a set of n rectangular items with width w j <= W and height h j, for 1 <= j <= n. The problem is to pack, without overlap, all the items into the minimum number of bins.
