find the optimal cut layout of a large sheet cut into smaller pieces with minimum scrape

Yesterday I released Smart Cutter
, my first iPhone/iPad app in the App Store
. The app is based on Algorithm 105
article I posted a few years ago which talks how to get the maximum number of small sheets cut from a large sheet with minimum scrape.
I took this algorithm and turned it into a small little tool for the
which should come in handy whether you are a
photographer printing multiple photos on graphics paper and looking for
the best print layout, a carpenter wanting to cut pieces of plywood from
a larger sheet, a tailor wanting to saw smaller pieces of cloth from a
larger size piece, or even a metal or glass sheet cutting worker.
To begin, simply launch Smart Cutter app into your iPhone or iPad device, specify the big sheet dimensions, specify the small sheet dimensions, and then tap the scissors button. Smart Cutter runs a state of the art optimization algorithm to generate the maximum number of small sheets from the original sheet while minimizing scrape. Tap once on the diagram and you should see the yield, which is the maximum number of small sheets you can get, the scrape percentage, along with the sheet dimensions annotated on the diagram. You can go back, change the dimensions, run it again, and watch the optimal layout change accordingly. It is actually fun to go back and forth trying different dimension combinations and watching the optimal layout changes every time. The task that can take you hours and hours of trial and error to find the best cutting layout, not to mention potential material waste, gets replaced by a small tap of the tip of your finger on your iPhone or iPad device. Best of all, you are guaranteed to get the one and only optimal cutting layout that ever exists for this combination of Big and small sheet dimensions.
If you like to review Smart Cutter for your web site, email me and I'll be happy to send you a promotion code.

For kerf allowance, I have developed an app geared specifically towards woodworkers needs:

Does the nesting account for saw kerf?

Your carpenter app for the iPad2 for 14.99 looks like something I might use one or twice a year. But if you added a simple calculator for the number of sheets required for a subfloor and the ability to record the address for the project -- I could probably use that twice a month. Measurements in feet and inches. Most floors are not simple rectangles, so would need to be able to add multiple measurements for one project. By being able to save the data to an address, it could save a couple of hours labor when re-visiting a job site for new changes. Also would be nice to be able to calculate carpet and pad or vynal or tile different sizes to cover the same area. Grain direction of carpet is necessary also.
Just a few thoughts for all your spare time. Ha! Ha! Just like my spare time I'm sure. Thanks for your time and a simple response would be great so I know if I should watch for the app upgrade.
Thank You again.
