Some people are fortunate. Others get married. ― belisarius


It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

I was tempted to edit your title: "Do rules rule?" But my nose is still bleeding as a result of a limerick. – belisarius

I am having trouble following the wording of this Question. Would you try stating the question differently in the hope that I understand? Can you give an example of the input and output that you want for a single case or a smaller problem?

comment Format-Size-Larger/Smaller shortcut disabled in M10?
I am adding the bugs tag because this doesn't work the same way across platforms, therefore this presumably is not an intentional change.

comment Bug? Side effects when exporting to .mx
No problem here either, same setup as Sjoerd. By the way do you realize that your use of CreateTemporary[]<>".mx" is making two files, one with the .mx suffix and one without?

@Tangshutao I certainly hope it is faster. :-)

comment Better way to test that a matrix is upper-triangular?
@Tangshutao Okay. I simplified my answer as the same (body) code will work in both versions, but you will need to replace SquareMatrixQ with your original argument tests, e.g. start with: utmQ[m_?MatrixQ] /; Equal @@ Dimensions@m :=
