My favorite subject has always been mathematics. Most importantly, I disliked writing essays during my school years. Nothing changed when I got to college. But I was fortunate to discover the bestessays ,which transformed my life. I frequently sought assistance in writing essays, but I also attempted to learn how to write on my own. It took a long time for me to figure it out on my own.

A world with lovely beans is waiting for you. LOL Beans is a fantastic game in which you race and fight against other players to reach the finish line. Avoid being shoved off by others by dodging, weaving, and jumping through the obstacles. The game is a lot of fun, with cute graphics, a lot of regions and servers, a good team behind it, and a lot of different obstacles and stages.

Ha ha ha. Whether you are being illustrated as a woman but still great work François Le Gall. click

What if Le Gall is an SMBC reader? Imagine seeing one of your greatest achievements being attributed to a cartoon person who not only doesn't even look like you, but is even the wrong gender! And has GLASSES!

How dare you be offended at something! I challenge you to the field of honor at whatever time you want, I don't care.

WOW....after reading the wiki-link...I thoroughly feel like a pig looking at a watch. (o~o)

The algorithm is described in https://en.wikipedia.org/wiki/Matrix_mu ... _algorithm. There you can also see a nice graph about how Coppersmith-Winograd came about in the early 80's, and read that the current record holder is a derivative of that algorithm:
The current O(nk) algorithm with the lowest known exponent k is a generalization of the Coppersmith–Winograd algorithm that has an asymptotic complexity of O(n2.3728639), by François Le Gall.
The suggestion that Le Gall spent 40 years toiling on improving C/W is indeed false; Le Gall is approximately (masters in 2003, PhD in 2006) 40 years old and I know for a fact the math curriculum in French grade schools isn't that good. The increase from 2.3728642 to 2.3728639 actually took him 'only' about 3 years, furthering research by Vassilevska Williams published in 2011.

Maybe the comic depicts his overly entitled mother.

What really puzzles me is the lack of stress on
these algorithms are only worthwhile for matrices that are too large to handle on present-day computers.
or the fact that mathematicians can get upset if a set of n calculations can actually take n calculations.

Maybe Virginia Vassilevska Williams, who got it down to the first number in the comic in 2010? I don't see any pictures of her wearing glasses, though, and her hair's not that gray.

I had to google the number in order to understand what this is about. It's this: https://en.wikipedia.org/wiki/Coppersmi ... _algorithm

It's a matrix multiplication algorithm with time complexity O(n^2.3728639).

Strangely, the Wikipedia article just lists the complexity improvements made over the years, but doesn't describe the algorithm itself even a little.

Worth noting: the person who made the improvement mentioned in the comic is François Le Gall, who looks like this:

The comic shows a woman.
