What's the planning problem? We're given a map of the world.

An alternative plan might be to go straight over here, take the detour around the block, and then go straight to the target location.

Guards ? Gore ?

The reason is the value of the goal is 100, 99, 98, 97.

Now let's go back to Romania and apply the A algorithm and we're going to use a heuristic, which is a straight line distance between a state and the goal.

Oh man...

I don't believe this. Kyoya?

What dynamic programming gives you is a plan for every position.

And Mama not dead a year? Who's she?

And you can see that it doesn't necessarily find the shortest path of all.

Now at some point we meet up with a goal. Let's say the goal is here.

In hockey and soccer, goals are counted as points.

You never intended to marry me!

Basket!

Gore ?

But it's gone in!

Here comes the second runner.

You must not lose sight of your goal in life.

So you want to know which of these five people is So

It's Secretariat at the finish!

That's the problem with goals they become the thing you talk about instead of the thing you do.

I'm not losing my link to Ethan Shaw.

Because we're not seeing a face. It is distant.

Goal Seek

And it's converging to much better results.

The perceived distance is much smaller, resulting all the way in a vanishing point that sits somewhere over here.

She's a wandering soul, looking for her mother...

In the discussion the accent was on unemployment.

Draw goal

We all want the same thing, Helena.

TEDxYouthDay, 60 events, unclear around the world over a period of 24 hours.

He's embodied that in all his work and kept it fresh, but not gone away from original things were.

like this one over here, which is a cube under perspective projection.

Or the mare. Or the finish line.

They've come thousands of miles on a perilous trip, risked life, health and property, spent months of the most arduous labor a man can perform and at length with expectations raised to the highest pitch have reached the coveted goal only to discover the fact that there is nothing here for them.

A real airplane that we could finally present.

It is Secretariat! He wins it by two and a half, almost three!

So if human need is the place to start, and prototyping, a vehicle for progress, then there are also some questions to ask about the destination.

And those enclosing lines that might be parallel in the physical space would result in their own vanishing point.

Let me look at a different maze, and this is not a car example anymore, but it's close to what we're going to program.

Without proof, the g value when I hit the goal node will be exactly the number of steps it takes to go from the start state to the goal node.

You cannot help when the goal is unknown

I finished last, Hermione.

For the goal, obviously, it is 0.
