The answer is this one. Two twenty is less than 229 or 239.

The farthest paths that have been explored, we call the frontier.

So 140 is the lowest.

Looking for new groups...

Then, when we consider a new path, we add the new state to the set of already explored states, and then when we are expanding the path and adding in new states to the end of it, we don't add that in if we have already seen that new state in either the frontier or the explored.

And we pop that empty path off.

Now, here's another representation of the search space and what's happening is as we start to explore the state, we keep track of the frontier, which is the set of states that are at the end of the paths that we haven't explored yet, and behind that frontier is the set of explored states, and ahead of the frontier is the unexplored states.

Now Tree Search represents a whole family of algorithms, and where you get the family resemblance is that they're all looking at the frontier, copying items off and and looking to see if their goal tests, but where you get the difference is right here, in the choice of how you're going to expand the next item on the frontier, which path do we look at first, and we'll go through different sets of algorithms that make different choices for which path to look at first.

You're going to help me find a new buyer for Scylla.

It starts off by initializing the frontier to be the path consisting of only the initial states, and then it goes into a loop in which it first checks to see do we still have anything left in the frontier?

Chimborazo!

True, we have added a path that ends in Bucharest, but the goal test isn't applied when we add a path to the frontier.

And that's the cheapest, so this one gets expanded.

DeLauer Diamonds is looking for a new ad agency.

It's around Westley, California, around Modesto.

So let's write down those three components.

You're going to help me find a new buyer for Scylla.

If I were to go newpage, we do the same thing.

It was... It was looking for the newspaper.

A final frontier begins in this hall.

I need to find a new job.

Be a traveller, not a tourist.

Again, we don't stop here just because we put a path onto the front tier, we put it there, we don't apply the goal test next, but, now we go back to the front tier, and it turns out that this 418 is the lowest cost path on the front tier.

Meyer is looking for a new investigator.

I am looking for a part time job so I can buy a new video camera.

If I'm Self, I'm looking for a new buyer.

We need a new babysitter.

It's final because once we reach it, it's limitless.

And that's why, now, the new breakthroughs, the new frontiers in terms of oil extraction are scrambling about in Alberta, or at the bottom of the oceans.

If it is, then we reset the new best test to be this smaller subset and the current best size to be equal to the length of this smaller subset.

One of the things that we did with the Ansari X PRlZE was take the challenge on that risk is OK, you know.

He is seeking a new position.

You can see the tree that is being expanded in that search.

lender, that has maybe similar terms.

And so at last mankind began the conquest and colonization of deep space.

We'll employ a new tool to increase productivity.

The answer is that we're not done yet, because the algorithm works by doing the goal test, when we take a path off the front tier, not when we put a path on the front tier.

Well, Marcel Proust has this wonderful saying that, The real voyage of discovery consists not so much in seeking new territory, but possibly in having new sets of eyes, new ways of seeing things, a new mindset.

Bell were looking to new technologies to optimize their revolution.

I'm looking for a gift for my father.

And if you're a biologist and know about sharks, and you want to assess, how much jeopardy am I really in here, there's one question that sort of jumps to the forefront of your mind immediately, which is (Video) Diver 1

Because sometimes, as Proust says, mystery is not about traveling to new places, but it's about looking with new eyes.

I talk on a lot of my videos about the fact that the brain is a scientist so you can use it as the scientist that it is and send it out on a scavenger hunt for new proof once you focus on the evidence or the proof to back up a new belief more of those proof and those experiences will be flowing into your experience as per the

All pay attention to this woman... Sarah Mandy...

We'd like to be able to say we're going to stop doing that and somehow find this route.
