See those two pins? Well today I'm going to... stick them in you.


Ok, let me come clean: Mr.Wizard is actually an alias of mine... I'm glad I can finally confess. ― Sjoerd C. de Vries

No, I'm Spatac... I mean, Mr.Wizard! ― R.M

I'm Mr.W, and so's my wife! ― acl


@Spartacus, it was not fixable. ― rcollyer

check again; I just fixed it. :-p ― Spartacus

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


No, but they nowadays let me turn off the lights at night; 24 hours of fluorescence was really starting to make me feral. Brett says I should also mention the tip jar... – Daniel Lichtblau Mar 13 '12 at 20:48

I am not to be the judge of that. The edit will automatically put this in the reopen review queue. If the community votes to reopen I'll be happy, however I don't intend to reopen this by moderator power unless the update is truly stupendous. ;-)

@David Pardon me, but that is not correct. Please see the addendum to my answer.

comment Evaluate recursive funtion as a whole before computing a recursive step
@kon the author of the post under which a comment is made is automatically notified, therefore using the @ notification for that person is redundant and the system automatically removes it. I'll try to return to this problem later but I've got other things to work on now.

comment Evaluate recursive funtion as a whole before computing a recursive step
@kon I have been attempting to adapt Leonid's unsortedComplement to handle the malformed removal without losing speed but I haven't achieved it yet. Incidentally are you using Mathematica 10?

comment Evaluate recursive funtion as a whole before computing a recursive step
@kon It does indeed seem to be a duplicate as written so I closed it as such. See the link inserted at the top for several methods that should be faster than what you were using. The complication of returning {0} on a malformed removal will take some additional thought but since it was added as an afterthought in a comment I feel the [duplicate] is appropriate.

comment Evaluate recursive funtion as a whole before computing a recursive step
@kon Unless I misread it that question appears to be a duplicate. There are faster ways to approach this. I'll get back to you after some moderator custodial work.

comment Evaluate recursive funtion as a whole before computing a recursive step
@kon It would appear that the vast majority of the time is spent on edit, so optimizing h is unlikely to be of much help unless it can be made to call edit less. Since you got the wrong output I suggest that the apparent improvement you saw was not due to greater efficiency but simply fewer calls to edit. I shall continue to play with this but I shall focus on edit.

@kon I'll take a look at it.

comment mathematica apply list of functions to the same arguments
This question has remained closed for over a year. As part of routine maintenance I shall delete it, unless you can edit this such that the community wishes to reopen it. I think some examples where naive Through fails would help.
