Yeah, so one of the interesting things about Libratus is that we had no idea what the bar was to actually beat top humans.

We could play against, like, our prior bots, and that kind of gives us some sense of, like, are we making progress?

Are we going in the right direction?

But we had no idea, like, what the bar actually was.

And so we threw a huge amount of resources at trying to make the strongest bot possible.

So we used C++.

It was parallelized.

We were using, I think, like 1,000 CPUs.

Maybe more, actually.

And...

You know, today that sounds like nothing, but for a grad student back in 2016, that was a huge amount of resources.

Yeah.

And, you know, talking about terabytes of memory.

So it was a very paralyzed, and it had to be very fast too, because the more games that you could simulate, the stronger the bot would be.

There were all sorts of optimizations that I had to make to try to get this thing to run as fast as possible.

They were like, how do you minimize the latency?

How do you package things together so that you minimize the amount of communication between the different nodes?

How do you optimize the algorithms so that you can try to squeeze out more and more from the game that you're actually playing?

All these kinds of different decisions that I had to make.

I think I used Visual Studio, actually.
