Packing Algorithms May Save the Planet
An anonymous reader writes "New Scientist reports on how competitions to devise better packing algorithms could help cut the environmental impact of deliveries and shipping. A new record setter at packing differently-sized discs into the smallest space without overlapping them has potential to be applied to real world 3D problems, researchers claim." Ok the title might be a little ridiculous, but the ridiculous packaging used to ship a few tiny objects by some shippers is pretty shameful.
I know many of you despise Amazon due to the one-click fiasco (and with good reason). But packing/packaging are one area where they're trying to get things right. When possible, order items that are packed using "frustration-free" packaging.
UPS has gotten itself a lot of press over the years about how it has saved fuel, time, and money with its routing algorithms. There was recently an article in Information Week about some of their technology. It is amazing how even a small improvement can save big money AND positively impact the environment. Routing improvements save time and money. Better vehicle maintenance plans. Less idling. This is the printable article. It has a session Id so I don't know if it will survive. http://www.informationweek.com/shared /printableArticle.jhtml;jsessionid=34SPUBGP0QJA2QSNDLRSKHSCJUNN2JVN?articleID=212900815

I'm working with 2D stock cutter from astrokettle (http://www.astrokettle.com/pr2dlp.html) and they have some very impressive algo to get the best out of you piece of you sheet. Give it a try.
Its not "practically impossible" to find the best solution. It is quite possible. The issue is that finding the optimal solution takes O(2^n), where n is the number of objects to be packed. So, for any large value of n, the calculation will take a prohibitively long time, but it will terminate.
This is in contrast to undecidable problems, which really are "practically impossible" to solve.
We all know what to do, but we don't know how to get re-elected once we have done it
So you won't see it on an aerial photo of the area, but you will definitely notice it if you sail through it.
Faster! Faster! Faster would be better!
