OK this is another example of -- the shortest path.
We have a b c h d f you these are the paths to each three and then a to d.
We have 11 and then eight is four etc..
So let's see how this works.
So a can go to a 0 2 that's usually that's the lowest it can go to be with three.
So it comes from B.
They can go to d with 11 it comes from a.
They can go to B with four.
So the smallest is a and then then we bring down the beak.
That's the next show choice that we're going to make as being the next smallest.
The B is three from a D.
It should be that B is A B is three from a.
So
again we don't have to fix that it's who is to mix.
So three is from A and then B can go to see.
And that would be 15.
OK because in three plus 12 that doesn't go to the D.
Well it does actually that B can go to the D and that's going to be 11.
That's going to be 11 but it could go from a four.
In other words you could do this and get 11 or you could do this.
I just have to choose one because they're equivalent.
I'm just going to leave it at that because that would be less so.
You know steps just the same amount.
I'm gunning for our purposes you can choose either one.
And for me it's still going to be for now we choose the next milestone on which as we bring that down
and then we can get connected the so would be formless six is 10.
We can connect to.
So that would be 6 3 6 Fehmi.
We have D is going to be one less if you take the path to it and C is still the same.
We bring down this which is the next lowest the six to any and then we check out the sixth form and
if we check out how to get there so now can connect to the with 7 because it's 6 plus 177 to H with
18 because that would be 6 plus 12 is 18.
And then the B doesn't change.
So this is there and we win them the next one was two which is D and D can connect to it through F like
we saw.
And that can also connect to C and that seven plus two is nine.
So we have that and then we have h which is 17 because it could connect from seven tenths of 17 the
next lowest is C's who would go to C and C K'NEX from D and that's 9 and it connects to age with 12
because you go 9 because 3 is 12.
So h is the low as is 12.
So in other words the path that we are taking is we are going to H goes from here we just trace it back
to c c comes from the C comes from the D comes from F D comes from F F comes from E and E comes from
a.
So this is the path that we would take to get the shortest amount you know in terms of these weightings.
And this is the path that would minimize the shortest distance.
In this case if you were to go a f d c h and this is the same system that we used in a test video to
set this up.
So there is the system and the hago.
