First-fit (FF) is an online algorithm for bin packing. Its input is a list of items of different sizes. Its output is a packing - a partition of the items into bins of fixed capacity, such that the sum of sizes of items in each bin is at most the capacity. Ideally, we would like to use as few bins as possible, but minimizing the number of bins ...
Computationally, the problem is NP-hard, and the corresponding decision problem, deciding if items can fit into a specified number of bins, is NP-complete. Despite its worst-case hardness, optimal solutions to very large instances of the problem can be produced with sophisticated algorithms. In addition, many approximation algorithms exist.

[27] On May 21, 2024, Daikin Industries, led by President & CEO, Masanori Togawa with Chief global group officer and board chair, Noriyuk Inhoue, celebrated its centennial founding with a commemorative ceremony attended by 2,000 at ...
Many of these problems can be related to real-life packaging, storage and transportation issues. Each packing problem has a dual covering problem, which asks how many of the same objects are required to completely cover every region of the container, where objects are allowed to overlap. In a bin packing problem, people are given:
In 2006, McQuay was acquired by Daikin Industries, a global manufacturer of both commercial and residential air conditioning equipment based in Osaka, Japan. Daikin had annual sales of $13 billion in 2009. [2] Daikin was named one of the 100 most sustainable corporations for three years in a row by Corporate Knights, Inc., from 2007 through ...
