AlgorithmsGiven a set of rectangular pieces, the two-dimensional bin-packing problem is to place the pieces into an open-ended bin of infinite height such that the height of the resulting packing is minimized. In this paper we analyse the performance of two-dimensional bin-packing heuristics ...
I started by looking up bin packing algorithms in theAlgorithm Design Manual: “Even the most elementary-sounding bin-packing problems are NP-complete. Thus we are doomed to think in terms of heuristics instead of worst-case optimal algorithms.” Ok, fair enough. Any suggestions ? “Analytical ...

1. In actual production, efficient packing algorithms can improve the utilization of raw materials and reduce production costs within an acceptable time. In a sense, the reduction of raw material consumption can have a beneficial impact on the environment1. Packing problems, also known as bin ...

A class of algorithms known as bin-packing algorithms can be used to determine efficient assignment of resources as between tasks and “bins”, which correspond to local resources that can be used to execute a task, e.g., those resources available in a computing node or group. Of particular...
