Version 10 empowered!


(also known as Spartacus)


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

"My main purpose of being here is in collecting the votes. I'd even go further and say that this is my main purpose in life." ― Leonid Shifrin

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

... but I am working with a large body of code written by an incompetent fool (i.e. myself, several years ago...) – Simon Woods


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 would love to see complete code to generate the first image in your post. Is it possible for you to share this?

comment Can I regroup terms into a sum?
Based on the answers received I don't think I understood the question. However none of the answers actually return an expression involving Sum which is what I thought wanted. Could you clarify your intent? Would you give a short example of the specific input and the output that would like the hypothetical function to produce?

comment Is 450 lines of code in one block too much?
I have been able to narrow the problem to the use of GraphData in the sense that removing those expressions prevents the hang/crash though of course it also breaks the program. This jogged a memory of another question about loading data inside a Dynamic expression causing a hang as the result of curated data being repeatedly (erroneously) loaded. I can't seem to find that now but I think it may be the same problem. I suggest you search for it.

Sorry for the earlier ignorant comment. On one attempt to run your code I got a message about Part failing and I thought I'd found the cause. If the code runs as intended in Mathematica 8 it seems you have run into a bug. If you report this to Wolfram support please let us know the outcome.

This is not the only problem but near the bottom of the code you have GraphData[;; 6] twice; I don't think this is syntactically valid.

comment Is 450 lines of code in one block too much?
I can replicate the problem. Unfortunately the code it not written in a well-modularized way that would ease debugging. Nevertheless I will see what I can do.

As m_goldberg said your syntax is wrong. Why don't you tell is what you are actually trying to accomplish and we can likely tell you how to do it?

comment What is the right place for user-defined init.m?
Files in $UserBaseDirectory will (should) also remain when you uninstall Mathematica or upgrade versions. They are also simpler to back-up.

comment Can I regroup terms into a sum?
I recall that a similar question has been asked before, and I do not believe that any general answer was (or can be) given. However if you give a sample of your expression I may be able to recommend a method.
