might I call on, say, two volunteers to kick us off with to say algorithms.

Yeah, And let's go over over here in front, if we may come on up.

So, Eric, behind these seven doors, we have placed in advance the number 50.

And we would simply like you the computer to search this array for the number 50 40.

I cannot answer that question at this time.

Oh, and so that the audience knows what's going on.

If you wouldn't mind taking the numbers out to sea.

None of them are close to 54 and amazing.

Now, if I may, Eric, what was the algorithm?

To you, Uh, you just go in a line from there until they're okay.

That was a very sophisticated answer to return We've not yet introduced.

But there's these different parameters that we want to optimize solutions for not just correctness, but what other property as well.

So was that the most efficient you could have done?

So at the end of the day, I have to look through.

Every single one was just by chance that the 50 was the last.

So it's it's unfortunate that they were all random.

And I didn't want to tell you because I don't want to bias your algorithm, one way or the other.

But not knowing if they're sorted and them not even being sorted means that, you know, Betts is the best you could do.

Look at all of the doors to find the number and question.

And maybe you could have gotten lucky if we had put 50 here.

But in the worst case, Eric was, of course, gonna have to do exactly that, searching all of the boxes.

Stay on stage with us, if you would for a moment and a round of applause, if we could for finding 50.

Theo, we need you not to look at the numbers because Brian needs to do a little bit of magic and he's gonna put some of the numbers back into the locker so literally everyone in the room will know what's going on except you at the moment.

But we're going to give you the added bonus this time off, sorting the numbers in advance.

So Brian is in the process of sorting some numbers for us.

The goal at hand in just a moment is still going to be the find the number 50.

I'm really just stalling right now because he's still doing this.

I don't really have anything interesting to say just yet.

We're so glad you could join us here today.
