Solomonoff induction goes from program to output to prediction weighted by program's length. It never goes from type of prediction to shortest equivalent program. It doesn't need to compute Kolmogorov complexities. (Well, more spe

One way to avoid that problem is to use interpolation between two frames computed by the physics engine.

Quirk was hitting a limit before 10 due to time costs, not space costs. Avoiding the matrices also saves you a lot of time because you can apply M 2-qubit gates to N qubits in O(M 2^N) time. Usually M is much smaller than 2^N (e.g. for the

So glad to see more hobby-level projects happening in the software/simulation side of quantum computing. I could criticize some of the design choices, but honestly they're all fine for 5 qubits. Quirk also started out with hacks t

Note: this is fixed in ES6. Using `let` instead of `var` will treat each iteration's variable as distinct: a = [] for (let i = 0; i <3; i++) a.push(() => console.log('hi ' + i)) for (let e of a)

In relativity, 'backwards in time' effects are ones that affect things in their own past-ward lightcone [1]. Only affecting things outside that cone might violate the light speed limit, but it won't violate causality. https:

Kinda. I think it would fail utterly in practice. The per-person incentives are all wrong. You're less likely to get picked if you ruin one of your kidneys, for example. "Donors" are going to be unwilling in general, and that

These are easily fixed by dove tailing through the programs and using an increasing-over-time cutoff. Not fixed in the "made practical" sense, but in the "made non-contradictory" sense.

I wasn't expecting this article to be about Sleeping Beauty problems and Solomonoff induction. There are people trying to apply real machine learning algorithms to real physics problems (e.g. [1][2]). This article is not about that. It

If you feed biased random bits into Solomonoff induction, the shortest surviving programs at any given point would tend to be things like arithmetic encoders that match the bias and specify just a bit more output. (Assuming you're not

Why would this put an end to that line of reasoning? I'd expect it to flare up the debate, not end the debate. They didn't disprove behavior being computed, they demonstrated that a class of data supporting it was useless. The nat

That's introspection. It's distinct from the hard problem of consciousness. Consider that it's not difficult to make computer programs that introspect. A quine is a trivial example. But since people argue over whether compute

In the case of QM, I think the concrete physical cases are all counter-intuitive. They trigger the wrong ideas and confuse people instead of helping them, e.g. by having them focus on malformed questions like "is it a particle or is it

It's just a joke about bugs being subtle and hard to find despite hiding in plain sight. I'm kind of impressed you spotted it; I wasn't sure anyone ever would (it's harder to see on some monitors than others).
