The technique we looked at so far was problem solving search over a state space using techniques

So far we've looked at the state space of cities in Romania a 2 dimensional, physical space.

We know how to solve this.

Now, I've told you what a successful plan looks like, but I haven't told you how to find one.

Here is the sliding tile 15 puzzle, and you can see this is a puzzle where you move these pieces around until all these numbers are in order.

A roguelike dungeon exploration game based on the books of J.R.R.Tolkien

We can say what actions would lead to that state.

And again, it's related to the analysis of graphs and paths, and using variance of depth first and breadth first search to answer questions about the graph.

I'll come back to that in more detail again when I talk about the bonus problem.

Commencing search.

Because kids are born curious.

The third problem is that many states recur in the search.

Another town, another name.

I thought she went back home, but she is working in that restaurant.

And it turns out that the basic strategy that we use for this algorithm is a kind of graph search.

Now, assume we search from left to right.

It seems very inefficient.

All right. What if it's two? We want to know if this graph two colorable.

This code here is for the bonus problem.

The government is still groping for a solution to the problem.

So, remember in problem solving, we start off in a state, and it's a single state, not a belief state.

How do you try to get a handle on extraterrestrial life?

Two nights previously our hustler Paul had an ambivalent task, to bin rummaging.

Phone imei to search when probing devices

You can see that the search algorithms do a great job of finding solutions to problems like this.

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.

And then the goal would be to own ISBN number 0136042597.

They explored the Antarctic.

Check that on the three side of the building. Is that all right? You got that?

Looking for alternative, but still searching for a victim on level 12.

Come on, search planes.

The Primes set out with one rule

You keep carrying on like you've been carrying on and it''s only a matter of time before Gigante's looking for you.

How can that help us get to our destination in Bucharest?

Problems are expected in their expedition.

If I run it with a heuristic function of all zeros I get back my original search algorithm.

There's a couple well known algorithms textbooks that cover those details.

I don't care what your problem is. Just keep goin'.

Lots of files is good. It keeps things clean. It keeps each file sane.

It was expanding out everywhere in the space and depending on where the goal is, we should expect to have to explore half the space, on average, before we find the goal.
