Ah, any such "expansion" would need more money, and the main job of the President of a university is to raise money. Soooo, we can conclude that the President of Columbia is trying to raise money. We ever expected something else?

At its core, the game theory of von Neumann is the saddlepoint result. There are two players, Red and Blue, for some positive integer n n moves, and an n x n matrix G = [g_ij] of real numbers of payoffs . So each of Red, Blue pick a mo

Amazing. Of course I've heard of Kernighan long ago, but this is the first I've heard of LKH. I did a lot in optimization, in my Ph.D. studies and in my career, but I dropped it, decades ago -- my decision was made for me by my c

Can look at the now old work of G. Nemhauser. His work was for combinatorial optimization and not just for exactly the traveling salesman problem (TSP). E.g., there is George L. Nemhauser and Laurence A. Wolsey, Integer and Combinatoria

I read the OP. Okay. I have a good track record in AI, about the best: I was right and for the right reasons! I got fairly deep into expert systems and said clearly at the time that I thought that they were, in a word, essentially junk

Calculus: I suggest just forget about "precalculus" and, instead, just get a good calculus book and dig in. There are two main parts of calculus, and both can be well illustrated by driving a car. In the first part, we take the

Thanks. And thanks for the URL to Feynman's lectures -- I lost my paper copy in a move. Yup, I understand that early on in quantum mechanics, we will get to both energy and momentum of these particles that have wave functions that

Thanks! Yes, it has begun to dawn on me that since d/dt e^(iwt) = iwe^(iwt) (frequency w, time t) that e^(iwt) is both an eigenvector of simple versions of Schrödinger's equation and also, essentially via Fourier theory, one axis

So, you did a search at some of the search engines and found some explanations for the computer jargon "middle click". Here is a point: Before doing such search, can't be sure will find a good answer. That was my point: Th

My guess for the meaning of a "middle click" was to click on a reference somewhere in the middle of the text of the reference, say, after the authors but before the journal. My second guess would be something having to do with a

The OP was talking about hundreds or thousands of icons -- tough to have an easy way to have meanings for all of those. Also the OP showed some icons -- it was not at all obvious what the meanings were. Right, for an icon, commonly, hoveri
