WebThis chapter deals with two classic problem: the bin packing problem and the cutting stock problem. Let us start with some definitions and examples. You are the person in charge of packing in a large company. Your job is to skillfully pack items of various weights in a box with a predetermined capacity; your aim is to use as few boxes as possible. WebThe Bin-Packing Problem (BPP) can also be described,using the terminology of. knapsack problems, as follows. Given n items and n knapsacks (or bins), with. Wj = weight of item j, cj = capacity of each bin. assign each item to one bin so that the total weight of the items in each bin does. not exceed c and the number of bins used is a minimum.

WebThe Bin Packing problem is NP -complete. More specifically: Theorem 8.1. It is NP -complete to decide if an instance of Bin Packing admits a solution with two bins. Proof. We reduce from Partition , which we know is NP -complete. Recall that in the Partition problem, we are given n numbers c1,...,c n ∈N and are asked to decide if WebTwo-Dimensional Rectangle Bin Packing. Ok, so here we deal with the Two-Dimensional Rectangle Bin Packing problem. In any bin packing problem, you are given some containers (in our case, the container is a 2D rectangular region). A set of objects (again, in our case, these are smaller rectangles) should be packed into one or more containers.

WebThe proposed approach was applied to several variants of the bin packing problem in order to explore its application to discrete constrained optimization problems.
