If you Okay, that's that's a plan.

Okay, so one about 23 if we could Okay, four in the middle of their 567 And let's see and lets me come up here.

You do it after and have a hand in the middle.

About eight volunteered by your friends.

Come on up.

All right.

So come on up, if you would.

And, Brian, if we could go ahead and equip our volunteers each with a number, we're gonna go ahead and see if we can't solve together the idea off finding an algorithm for sorting the numbers at hand.

So in just a moment, each of you will be handed a number.

In the meantime, let's go ahead and just say, a quick introduction, who you are, and perhaps your house cruise.

Studly house from Germany.

Yeah, Curtis, Just here visiting.

Wonderful.

All the freshmen.

Apt Accord from Turkey for a foe ho from Detroit.

Nice.

Alison Hollis, cause I'm first year from Cleveland Cloud.

I'm in Mauer and I'm from Virginia.

I'm roadkill.

I mean, Wigglesworth and I'm from Atlanta.

I'm your Well, I'm also from Wigglesworth.

And I'm from New York.

Bonnie, aiming low line from Beijing in Ann Arbor.

Wonderful.

And I'm noticing now is you might be too.

We have nine volunteers on stage, so we're gonna go ahead and solve this.

That's okay if you What's your name again?

Bonnie.

Come on over here.

You're gonna be maybe my assistant, if you could, as we sort these elements.

Let's go ahead and give you the mike here.

Each of you has been handed a number that happens to match with this, which is just so unsorted list of numbers.

And let me just ask that are eight volunteers here.

Sort yourselves.

Go.

What are you?

I have direct them after this.

Excellent.

Very well done.

Okay, so let me ask any of you and will hand you the mike if need be.

What was the algorithm used to sort yourselves human intuition.

Okay.

Nice.

Nice.

Other formulations.

Yeah, doing.

I just checked.

If, like the person who's left me like who is supposed to be larger than me is larger than me.

And if he was larger than me then I stayed there And if I was larger than him, I just switched places with him.

Okay, I like that.

A sort of locally optimal approach where you just kind of look to the left and right and sort of fix any transposition, zor mismatches.

And in fact, let's go ahead and try and apply that same idea.

Can all eight of you, Reese, order yourselves just like that?

So that you're standing below your number so that we're undoing the human intuition that we just executed.

And now let's go ahead and say, All right.

So, bunny, if you don't mind helping direct us there to direct us here, we clearly have now an unsorted list of numbers.

Let's just bite off this problem one bit at a time.

So, for instance, YouTube your names again.

Tress and Curtis.

So you guys are clearly out of order.

So what would be the locally optimal solution here?

They were switched Shorter's OK, Please do that.

All right, Now, let's consider six and eight.

Uh, they're fine.

OK, 85.

Let's again please switch again.

Eight and two.

Such Okay.

Eight and 78 and four.

Such eight and one.

All right.

So have we solve the problem, okay?

No, obviously not, but is it better?

Are we closer to the solution?

I mean, I'd argue we are closer because right, like, eight somehow made its way all the way to the correct destination, even though we still have kind of a mess here to fix.

But notice that the solution got better in this direction and a little better this direction.

But we're going to do this again.

So, Bonnie, can you direct us once more?

Uh, yeah.

So if you would proceed from this order, uh, you two would switch five and 66 and to remain, and then the next person's seven and four horse, which I seven and one inch and then.

All right, so now are we done so?

No, But look, the problem is getting better.

It's closer to solution, because now we have eight in place and seven in place.

So we've taken a bite out of the problem, if you would.

Now we can do this a little more rapid.

So if you want to tell everyone what to do perro eyes pretty quickly.

So everyone Human intuition, if you will.

But let's do a pair wise.

Okay?

Sure.

Could everyone, if the person on your right is smaller than you, switch with them and then do that again.

Good.

Do that again.

Again.

Good.

Uh, yeah.

On, then.

Yeah.

So even though we allowed it to get a little organic there at the end Now, is the assorted Yes.

So maybe a round of applause for our volunteers here.

And thank you, Bonnie, especially.

Thank you.
