There are probably a lot of different ways to look at it. One perspective is that easy problems usually involve convex sets (or minimizing convex functions, which is pretty much the same thing since the solution set is guaranteed to be conv

What about Atlas ? http://www.bostondynamics.com/robot_Atlas.html EDIT: Also for the Motoman, is it possible it needs so much power because of how fast it can move that 15 kg mass around ? There's no beating conservat

The implications would be far greater than that if he were right. An efficient algorithm for an NP complete problem would mean that you could find global optima for general non-linear functions. That would very likely lead to superhuman A

Is the hardware really that much of a problem ? It seems like the Boston Dynamics robots are already very far along on the mechanical aspects. I've also seen videos of industrial robots which appear to work with greater speed and agi

The paper has pages of formalism about interpreting SAT in probabilistic terms that feel like they probably don't add anything to the problem. I'm not inclined to work through all of that either but I think it's very likely

I'm not very familiar with the discrete logarithm problem but it seems to be fairly generally true that many problems which are easy in the continuous case become hard when you try to restrict the solutions to a grid. Even solving the

It's easy to formulate 3-SAT as an LP feasibility problem. The problem is that you need solutions in which all variables are either 0 or 1. That makes it an integer or 0-1 LP problem and such problems are NP hard.

I don't have any information or opinion regarding the choice of cpu but I doubt your crashes are due to not having ECC, unless the machine has a bad memory module. It's more likely to be a software problem, maybe driver related.

I've heard of organic semiconductors but I had no idea they had advanced to the point where they could be used for an SoC. Is 2 microns small enough for an ARM core ? This sounds like it could become very important. Do you know of any

Can someone explain what this technology is about, I wasn't able to get any sort of understanding from this post. What exactly are they printing ? Are the transistors actually made of plastic instead of doped silicon ? If so what fea

Note that he's primarily taking about HF gas, not the aqueous solution. Aqueous hydrofluoric acid is certainly not to be trifled with but I don't think it's in quite the same category as some of the other substances this guy

60 bits is only about 8 characters. I've found that it's easy to memorize 20+ random character passwords if you use them everyday, and I've always had quite a poor memory.

The problem is with the usage of the word "communicate". Normally communication would mean "transmit information". Quantum entanglement does not allow this. With entangled particles a measurement on one instantly chan

I'm not an expert but quantum entanglement definitely does not allow FTL communication. I believe quantum key sharing requires a classical channel in addition to the quantum channel, hence no information is transmitted faster than ligh

If this stands it seems like the Feds are going to be able to prosecute anyone who ever misleads someone in a commercial transaction for "wire fraud" and potentially send them to prison for 20 years. Is this really the country we

The regulation you linked to appears to date to 2010, long after analog phones had been replaced. 18 U.S.C. 2512 may be older but I wonder why such a regulation would have been issued so recently. Also if this regulation is intended to impl

I actually agree with much of what is said in this article but I don't see how it amounts to an argument against cryonics. While there's no proof that freezing preserves sufficient information to reconstruct a mind/brain ther

That's a very interesting result (assuming it's correct). It certainly agrees with intuition based on analogy to boolean circuits where, for example, the parity function requires exponential circuit size for shallow circuits but o
