I've been a professor of mathematics at The University of North Carolina - Asheville since 1997. I've been using Mathematica since I started graduate school in mathematics at Ohio State in 1989. At that time, we used version 1.1 (as I recall) to teach calculus in our Calculus and Mathematica classes. I've used it pretty much continuously in my teaching and research since then.

In addition to my posts on SE, you can find some of my papers, teaching notebooks and other Mathematica based oddities strewn throughout my website.

In recent years, I've also worked as a part-time consultant to Wolfram Research focusing on development of mathematical content for WolframAlpha.

comment Conversion of 3D plot to 2D Contour Plot
@user85503 thing[[position]] represents part extraction. If you execute Short[InputForm[pic], 4], you'll see that, internally, pic has the form Graphics3D[GraphicsComplex[pts_,_],_]. Now, pic[[1]] grabs the GraphicsComplex (since it's the first argument of Graphics3D) and pic[[1,1]] grabs the first argument of the first argument, namely the points - which is exactly what we need.

Artes is correct that it's nice to see code in the question. Not only does it show some effort on the part of the OP, but it also lends context to the question letting the person answering the question know the appropriate level to write their own code. As I did encourage Javad to ask a follow up to this question, I'll provide an answer soon.

No biggie - you'll probably be an expert one day!

Please don't roll back my roll back! Honestly, it makes no sense for two reasons. Your original question refers to quite a specific operator so changing the operator wastes the efforts of those who answered the question. Secondly, this question has been closed so no one can answer it now anyway. If you have another question, simply open a new question.

@Schwarz The Mod[Total[Table[value[gen - 1, v], {v, adjacentVertices[u]}]], 2, 1] business sets the new value to either 1 or 2, depending on whether the sum of the adjacent nodes is even or odd.

I've rolled back your question to it's original version, as I think your change of dimension is significant enough to warrant a new question. Feel free to open such a new question! Furthermore, no one can really answer this one, as it's closed anyway! (Not that I agree with the closure.)

@JavadKazemi I think the same basic idea should work, though it would be nice to have a specific example in mind.
