WebThe two-dimensional bin packing problem (2D-BPP) is decomposed into a master problem and several subproblems. The master problem is a (one-dimensional) BPP, which assigns items to bins. Feasibility of each bin assignment is then checked in a separate two-dimensional orthogonal packing/knapsack (2D-OPP/2D-KP) subproblem.

"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 problem has many applications, such as filling up containers, loading trucks with weight capacity constraints, creating file backups in media and technology mapping in FPGA semiconductor chip design.
