#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

about Rule 30, I would say this is one of those cases where the money is not the main point, but it just helps motivate somehow the investigation.

No, it's $10,000 for each.

It's just, you know, will it ever become periodic?

Second problem is, are there an equal number of black and white cells?

#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

Down the middle column.

Down the middle column.

And the third problem is a little bit harder to state, which is, essentially, is there a way of figuring out what the color of a cell at position T down the center column is with a less computational effort than about T steps?

So in other words, is there a way to jump ahead and say, I know what this is going to do.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

You know, it's just some mathematical function of t. Or proving that there is no way.

#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

Or proving there is no way, yes.

#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

But both, I mean, you know, for any one of these, one could prove that, you know, one could discover, you know, we know what rule 30 does for a billion steps.

#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

And maybe we'll know for a trillion steps before too very long.

#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

But maybe at a quadrillion steps, it suddenly becomes repetitive.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

Yeah.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

You might say, how could that possibly happen?

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

But so when I was writing up these prizes, I thought, and this is typical of what happens in the computational universe, I thought, let me find an example where it looks like it's just going to be random forever, but actually it becomes repetitive.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

And I found one.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

And it's just, you know, I did a search.

Lex Fridman Podcast
#89 – Stephen Wolfram: Cellular Automata, Computation, and Physics

I searched, I don't know, maybe a million different rules with some criterion.
