Tom is coloring a picture.

God s coloring. And who gives better coloring than God? And we are devoted to Him.

A three coloring of planar graph isn't any easier than three coloring in general graph, it's NP complete.

Any possible 3 coloring, corresponds to the truth assignment.

Indeed, I was eagerly coloring the sketchbook in black.

So any possible truth assignment, corresponds to a 3 coloring.

We illustrate AlMS' progress by coloring in the countries of Africa.

What about coloring a graph with four colors if its a planar graph.

In this formula now as a whole has a satisfying assignment, has an assignment that makes this whole expression true if and only if there's a coloring, a 3 coloring of that graph.

And she starts doing all these different drawings and does color patterns and coloring books.

What they're getting at is that on the back of this crab the foodstuff here is this very strange bacteria that lives on the backs of all these animals.

But the way we can fix it is instead of coloring the six black, we color it red.

We're able to assign colors to all these nodes so that none of the coloring constraints are violated.

You each are given an identical strip of blank paper and begin coloring parts of it with crayons.

Well, we take this three dimensional stack of images and treat it as a gigantic three dimensional coloring book.

Which is, as the coloring or paint on the surface, shading. This is what the shape would look like if

And I'm coloring these small windows blue if another virus shares an identical sequence in its genome to that virus.

Since 3 coloring is an NP and SAT is NP complete, meaning that it's NP hard, it has to be the case that we could use SAT to solve 3 coloring problems, but it's actually a little bit interesting to see how you might do that.

For example, assigning the variable a red to true, a green to false and a yellow to false means that we're coloring the a node red, and so once we've assigned true values, trues and falses to all 12 of these variables that corresponds perhaps to some coloring.

Now in the beginning of this unit I did a little magic trick having to do with coloring in region in a map.

What you see here is a coloring, which is the output of a machine learning algorithml that identifies driveable terrain in the desert.

Each morning the manager of this gallery substituted some new picture, distinguished by more brilliant or harmonious coloring, for the old upon the walls.

You were supposed to draw the palace, the Gyeonghoeru, etc., but I was coloring everything in black, so he dragged me out of the group.

A new correspondence over here gives us different strength as indicated by the different coloring of the links and another relaxation step gives us better cluster centers.

And now, what I'd like to do is show you the different ways of coloring these either allow the rest of this structure to be colored with three colors or not.

I added this new function called gray_style, and we'll come back to this for the bonus question but this is just a little function I wrote to alternate the coloring of rows in the Ul.

In fact, you have to be a little bit careful here because if we assigned two of these to true, which is a perfectly reasonable thing to do in a boolean formula, you can't really interpret this as a coloring except for may be a is orange, but that's not really allowed.

There is nowhere to dig, so you must dodge the enemies and avoid falling to the concrete at the wrong time. Try to keep the enemies together. If an enemy has gold coloring, he is holding a nugget. He might drop it as he runs over the concrete or maybe at the top of a ladder... patience, patience!

This problem is sometimes called map coloring. and just to remind you, the idea there is that each of the region in the map we're going to assign some color to it with the constraint that there can't be the same color in two adjacent regions on the map. because then it would kind of make it look like one big region.

Since this one is black and this one is blue, this one is forced to be red, which means this one's forced to be black which means this one's forced to be blue and now we're in good shape because this one is black and this one is red and now we have a valid coloring, actually no matter what l₂ is colored.

What we have to do now is given these 12 variables, we have to create a formula that is true if and only if it corresponds to a valid coloring, meaning that both exactly one of each of these triples the variables are true and there's no collisions for example, we can't have a colored red and b colored red because they're connected by an edge.
