Okay, guys this is Discrete Optimization, week eight, sorry for last week,
I was in China again and we had absolutely no internet connection.
I couldn't even download slides last week.
So one of the first things that I want to tell
you guys this week is that we are so proud, okay.
So this is amazing where we are at this point, look
at this graph okay, we never thought we would get there okay.
So this is around 700 people now,
getting a certificate and when you look at this,
this is around 200 getting the distinction, this is amazing.
Right?
So we never thought we would get there, this is very, very
high numbers, we are really so proud of what you guys did.
This is amazing, Okay?
So we are really, really, really excited.
you've seen on the forum the t-shirts, I love them, you know they are beautiful.
Look at this one, even you know I am color
blind but I can see the colors on this one.
They are so bright, I love this color and stuff.
Of course, we are already ordering these
t-shirts ourselves okay, so look at this one.
The other one is actually, and thanks for the
people who actually submitting those solution, Alexli probably here.
And so this is the, this is the
[INAUDIBLE],
the TSP one also completely crazy t-shirts.
You know, once again I love these t-shirts, okay.
You can order them.
All the instructions are on the website if you are interested obviously.
let me talk a little bit about the
other stuff about what we're going to cover today.
We're going to talk about the post-course survey, the TA program,
and there will be an entire video on this one.
I urge you to look at it, you know. And then other opportunities you'll see,
and then some of the statistics that I'm giving you every week, and I'll
talk a little bit about the fact that this is the final week, okay.
So post-course survey, I think, you know, it's very important that we
understand exactly how you felt about the class and the various topics.
You know, if you want more details, less details, if this is covered the same
level where you want more information, give us
that feedback, you know, this is really important.
Same thing about the assignments, which ones were too tough, which ones were
too easy, you know, do you want more, really or do you want less?
you know, you know, basically give us as much feedback as you can.
Also once again you can post everything on the forum, we
actually read this all the time, okay, we are really obsessed with
this thing I think you notice, we read the first, first thing
in the morning, you know late, you know last thing before sleeping.
so put as many
comments as you can, tell your stories and and, you
know, we can tell you that we read everything, okay.
so the TA program, okay so there will be an entire video there so
what we want to do is improve the class so we want your help, okay?
So, there are various ways you can help, you know there are very, various
forms of commitment that you know, you can do and look at the video.
We going to cover these things but it can be as
easy as just participating in the
forum, answering questions, giving hints to students.
To something when you can really shape the class and I
will tell you in the other video what that means, okay.
But this is, you know, you can have a big impact
on the class and I'll cover that in the other video, okay.
So, but this is something we strongly believe
in, you know, the teach assistant programs are
making a huge difference in practice, so you
know, just watch the video please, okay, good.
yeah, right, okay.
no opportunities you know, most of you know
that I'm professor here at The University of Melbourne.
I have another job actually which is
leading the optimization group research group at NICTA.
It's sup /g, it's essentially NICTA is a national ICT city center in Australia and
is basically collaborating very very closely with you
know the main universities and the top universities
in Australia.
Visit university of melbourne, the ANU, and
the university of new software in Sydney.
So essentially this group is like a national group
of like 60 reseracher at this point five professor.
And these professor are like vampires right, they like
young blood and young blood for us well is students.
Okay, so we love students and we are recruiting heavily students okay.
So if you are interested okay,
the Masters and PhD students, you, you, you
would be enrolled in one of these universities and
you would get you know for instance scholarship
From NICTA, if you get into the phD program.
So if you're interested in that, you know you can email,you know Sandra, who is
the coordinator of the group, really the
brain of the group essentially for more information.
There are also optimization internship at NICTA, for four ,six
,12 months, make sure you want to do a PHD,
you can come and see what it means to do research in such a group.
And once again you can email us for more details.
And finally, some of you have been so good that Phil Killby who has actually
been leading the logistic part of the group
was like "woah these solutions are really nice.
I want these people to work for me" so if
you are interested in logistics, like in the VRP assignment, okay.
So you can talk to you can talk to once
again send an e-mail to Sandra and Phil will look
at your applications and decide if you, you know, if you want to, if you can join
this, this four month internship that he's actually promoting, okay?
So, once again these opportunities in, you know if you are
you know, if you want to pursue more optimization with us.
Okay?
Now let my go back to the statistics now.
This is the number of students active in assignments, okay?
So this is, you know, basically, you know,
very stable at this point, okay? slight decrease, okay?
this is the total submissions graded, okay?
And so there is this very bizarre thing here, right, so
that's certainly, we have a lot more submissions, so we will like.
What's going on?
Okay, and this is the submission per active student, same thing.
Okay, so what is happening?
Okay, so this is the total number of
submissions by people who are submitting like crazy,
okay, and so you see top, you know, this is the second rank,
this is the third rank, so about you know, 1500 for the second rank.
And this is an interesting point, this is the first ranked student.
This student has submitted 190,000 assignments, okay,
soultions, over the course of this class.
Okay, and so this is
the submission over time, okay, so this is the beginning and then
[SOUND]
and this is a log scale right.
So this is a, so this number, this increase kind of crazy.
Right? So what happened?
Okay, so what happened is that this student actually
had a very nice program sending solution all the time,okay.
Every time he would find a solution he would send it.
You can do that with the infer structure that we have,
probably it's not a good idea but still you know, you know.
This is what happened and we took a little time to actually notice this.
Okay, yep so this is the Participation
per Assignment you have seen this graph before.
it's very nice you know like 850 for the Warehouse Location okay, so this is a
large number,if you can keep that number for
the last assignment that would be terrific, okay?
650 for the VRP so which is also good.
Some of the Puzzle Challenge are growing up, that's also good, okay,
so you can get a little bit more points for your distinction,
see if you want to do that.
Okay, so keep these number little bit up and we'll be really, really, truly happy.
one of the things that we have to tell you is
that on August 20, all the submissions will stop counting toward your
grades, so you have to submit before August 20, that's the last
day that which, you know, the submissions will count for you grade.
You can keep submitting, right, so but that won't,
that won't count on for your grade but you
can see oh, you know if I had a little bit more time I could have got a ten or okay.
after that, after August 20 we'll take a couple
of days and generate all the certificates for you guys.
the course content remains open. You can keep submitting.
You can keep looking at everything, okay.
But, your certificate won't be reissued, okay.
So August 20 is our deadline for getting a certificate, okay?
So you can cram a lot of work this week to just you know
get where you want to be.
the next session probably in six or 12
months so the course will remain open until then.
Once we go to the next session, you know the current
section will, will become, the current session will become inaccessible, okay?
So essentially we leave it open as much as we
can and at some point we transition to the new one.
Okay. So thank you.
You know, I think it was really a great week.
We'll have one more mail back
probably last week. next week.
For actually summarizing everything.
But you know, most of you are ready to go to the next step in optimization.
And once again, I love this graph you know.
Thank you, guys.
