Okay. 
So, this is discrete optimization Mail 
Bag for Week 6. 
a couple of updates. 
Nothing major this week. 
so, we going to look at the graphs and, 
and, and talk a little bit about them. 
this is the number of students active in 
assignments. 
Little bit of a drop there. 
so, you know, this is leveling off. 
So, this is nice. 
this is the total number of submission 
graded that's increasing obviously. 
a little bit less than last week. 
Okay. 
And this is the number of submission per 
active students. 
We have a drop for the first time. 
Okay. 
Probably we made a mistake. 
We gave you, you know, kind of an 
extension, and you all took off on 
vacation on a nice beach, right? 
So that's what I'm hoping here. 
And we're going to go up next week again. 
Right? 
So, this, this are the numbers. 
The numbers are looking good. 
So, let's say TSP is above 1000 for 
everyone. 
Warehouse location is getting very 
healthy numbers like 600 and above. 
Okay. 
That's good. 
VRP, we are already looking at at 350, 
400. 
I think overall we have already something 
like 500 students who are really in, in 
good shape overall. 
So, this is kind of very nice. 
Okay. 
So these numbers are growing up, so this 
is good. 
This is the curve. 
Okay. 
not much happening at the hat, but what 
is happening at the tail is very nice. 
Okay. 
So, what is, what you, you know, what, 
what we wanted last week is happening, 
this tale is lifting. 
And when you look at this thing here 
right. 
So, this is, this is kind of thick. 
Okay. 
So, for the last assignments, we had a 
very substantial chunk. 
Okay. 
So, the number of assignments that have 
been completed compared to last week as, 
as kind of you know, same number last 
week, same number this week. 
So, this is moving up nicely. 
Okay. 
So, steady progress you know, very happy 
to see that. 
We need to lift it more, right. 
because we want to get as close as 
possible to this you know, black line at 
the top. 
common questions about certificate, there 
were a number of them in the last week. 
So, to get a regular certificate, you 
need 224 points. 
Okay. 
And anyway you like. 
You do whatever you want to get those 
points, and you get a certificate. 
Distinction is 300 points, and you can't 
get more than 30 points from the extra 
credit. 
And the reason we have that is that this 
guarantees that you'll devote 75% of ten. 
Okay? 
So, we don't want you to get all tense, 
but we'd like you know, a very large 
proportion. 
There are some of the assignments that we 
know are really difficult. 
You know, the largest TSP, or some of the 
really challenging warehouse location 
problems. 
so, so, essentially 75% is really, really 
outstanding in this class. 
Okay. 
so, there was steady progress on the 
assignment. 
Very good, very good work. 
I think you should also look at some of 
the traits that you know, we, we noticed 
this week on visualization. 
There are some beautiful visualization up 
there. 
this is something that we mentioned 
during the class. 
You know, it's also always very useful to 
actually visualize what is happening. 
When you visualize, you can identify 
bottle neck you know, I told you many 
times in this class. 
Sometimes, we you know, we've spent hours 
and hours looking at this screen trying 
to find patterns. 
What is happening. 
Why are the, why are the algorithm 
working that way? 
You know, when you visualize, you see 
these things. 
And you know, if you look at these 
thread/g, people have done a really good 
work in visualizing some of the results. 
And this is something that you can think 
about. 
You know, when you are starting doing an 
assignment, just try the visualization at 
the same time. 
It doesn't take very long, in general, 
but it, it really informs you about what 
the algorithm is doing. 
Okay. 
So, keep the good work. 
I'll see you next, next week. 
So, this is the final stretch. 
Right? 
You can look at the assignments again. 
revise all of them. 
I saw, I saw on the forum that some of 
you were actually doing that. 
Keep doing that you know, that can make a 
big difference in the end. 
And now, you can look at them in a more 
relaxed fashion as well. 
Okay. 
See you next week guys, keep the good 
work.
