photonics is here

Told ya told ya. Didn't take long, either.

This gadget here, can solve the traveling salesman problem at the speed of light.

All that money they're spending on data centers, is going to be pissed away. This gadget will work on a 9v battery. Or even a 3v battery.

Here's the original paper.

Programmable 200 GOPS Hopfield-inspired photonic Ising machine - Nature

An architecture inspired by Hopfield networks based on a programmable, stable, room-temperature optoelectronic oscillator-based photonics Ising machine is introduced that can be used to efficiently address optimization and combinatorics problems.

This is an "Ising machine". It solves combinatorial optimization problems. It's exactly like a Hopfield network

Meh.

Wake Me when you guys break the first warp barrier.

Otherwise:

Meh.

This is pretty impressive stuff. 256 nodes at 200 giga-ops.

256 nodes means 256 cities, in a traveling salesman problem. With 256 cities, there are 256!/2 possible routes, which is about 10^500. Give or take.

Otherwise:

In the time you can finish that drink, say 10 minutes, this chip can solve a million such problems.

Compare:

An exact method like branch-and-cut, on a supercomputer, will take hours to days for a single solution.

A heuristic method like Lin-Kernighan will take seconds to minutes but it will only give you a ballpark solution. Which is probably good enough for limb trajectories in most cases, but you need the answer in milliseconds to keep up with the real world.

Tik-Tok.

They are using that TECH now instead of GPUs.

It should lower the prices of GPUs.

Belive me, they won't get your math skills. I once told my daughter (14 yo at the time): studying math and science is like studying God's work

I'm so glad she did not fully grasp my edict. Good women bear our children, and they must be nubm to this fact of life.

Go with god, be with god, and come back with...

lol

That's the other guy, that's Scotty, he's the engine guy.

You never saw him fix the computer, did you? Spock wouldn't let him touch it, he drinks too much.
