gcc will avoid FMA if you specify `-std=c17` (or another C standard, instead of the default "GNU" variant). Note that it has to avoid FMA in that case because fusing (a * b) + c would not comply with the C17/IEEE-754 spec (

I don't know how they do it, although the reddit commenters do mention IR emitters/reflectors in the ad panels being used to create a mask. What I did notice is that the system commonly has very slight glitches around player bodie

Sorry, I meant that those two books seem to be "classics" that are often used as references in graduate courses.

For theoretical continuous/nonlinear/convex optimization, your #1 is the bible, together with "Convex Optimization" by Boyd & Vandenberghe. However, beware that both are grad textbooks. They can be tough going at t

I looked for such a tool a couple of years ago and did not find any. As other comments indicate, this one may not yet be fully general-purpose. Could anyone here point me to an alternative? Something that generates rss or atom from HTML fil

> These "best cases" are hand-tuned for the domain by algorithm experts - right? Correct. It is arguably more than just "hand-tuned". The algorithm I mentioned, LKH, was entirely designed for TSP, and I'm not awa

For context, the tests here are performed on 50- and 100-city instances, as they are limited by current GPU memory sizes. Meanwhile, the best heuristic code for TSP [1] frequently provides optimal solutions to 100k-city instances ("heu
