I agree that it is still unsolved, from a practical perspective. I think both sides (the MD vs. ensemble sampling) have incorporated techniques that the other side uses to improve …

Yes, for sure. In practice (and not at the 50,000 ft. level), you do try to include the multimodalities — you don't _really_ just use E[quantum_energy(r)]. But you ARE still relian…

That's a good question and there are a number of ways to try to tackle this. One of the main reasons you cannot do QM simulations directly is that the high quality methods can cost…

[Disclaimer: I used to work at D. E. Shaw Research from 2011-2016] The early Anton 1 numbers of 17us/day on 100K atoms were huge leap forward then. At that time, GPU-based simulati…

Thanks — hope you enjoyed the post!

This seems extremely contrived and at best misleading, if it is meant to be more than an exercise to teach someone to code. If there were a function that could produce subsets of p…

While the analysis contained in this article is rather arbitrary, blustery and imprecise, there is a mechanism by which blockchains can serve as 'partially synchronized clocks.' On…

The diagrams remind me of performing a Dehn twist. Perhaps what you're doing at each grouping corresponds to a Dehn twist on the Tonnetz? Of course, since the Tonnetz is a particul…

I should point out that OpenAI put out a blog post / paper suggesting that genetic algorithms can perform similarly to backpropagation for Atari/Q-Learning tasks: https://blog.open…

Doesn't this article feel like it was written for Yahoo's benefit? Since they have a blinded bidding process (See [1]), it seems as if this article could help drum up higher bids. …

I should correct myself: It is extremely unlikely that they are the biggest fund based on their fundraising history.
