1
00:00:00,110 --> 00:00:04,330
Okay, guys this is Discrete Optimization,
week eight, sorry for last week,

2
00:00:04,330 --> 00:00:07,830
I was in China again and we had absolutely
no internet connection.

3
00:00:07,830 --> 00:00:11,590
I couldn't even download slides last week.

4
00:00:11,590 --> 00:00:13,720
So one of the first things that I want to
tell

5
00:00:13,720 --> 00:00:15,980
you guys this week is that we are so
proud, okay.

6
00:00:15,980 --> 00:00:18,960
So this is amazing where we are at this
point, look

7
00:00:18,960 --> 00:00:22,560
at this graph okay, we never thought we
would get there okay.

8
00:00:22,560 --> 00:00:25,070
So this is around 700 people now,

9
00:00:25,070 --> 00:00:28,006
getting a certificate and when you look at
this,

10
00:00:28,006 --> 00:00:31,780
this is around 200 getting the
distinction, this is amazing.

11
00:00:31,780 --> 00:00:31,990
Right?

12
00:00:31,990 --> 00:00:35,080
So we never thought we would get there,
this is very, very

13
00:00:35,080 --> 00:00:38,480
high numbers, we are really so proud of
what you guys did.

14
00:00:38,480 --> 00:00:39,560
This is amazing, Okay?

15
00:00:39,560 --> 00:00:41,279
So we are really, really, really excited.

16
00:00:42,730 --> 00:00:46,800
you've seen on the forum the t-shirts, I
love them, you know they are beautiful.

17
00:00:46,800 --> 00:00:48,450
Look at this one, even you know I am color

18
00:00:48,450 --> 00:00:50,220
blind but I can see the colors on this
one.

19
00:00:50,220 --> 00:00:52,740
They are so bright, I love this color and
stuff.

20
00:00:52,740 --> 00:00:54,285
Of course, we are already ordering these

21
00:00:54,285 --> 00:00:56,680
t-shirts ourselves okay, so look at this
one.

22
00:00:56,680 --> 00:00:58,170
The other one is actually, and thanks for
the

23
00:00:58,170 --> 00:01:01,910
people who actually submitting those
solution, Alexli probably here.

24
00:01:01,910 --> 00:01:03,800
And so this is the, this is the

25
00:01:03,800 --> 00:01:03,812
[INAUDIBLE],

26
00:01:03,812 --> 00:01:07,680
the TSP one also completely crazy
t-shirts.

27
00:01:07,680 --> 00:01:09,620
You know, once again I love these
t-shirts, okay.

28
00:01:09,620 --> 00:01:10,530
You can order them.

29
00:01:10,530 --> 00:01:13,420
All the instructions are on the website if
you are interested obviously.

30
00:01:13,420 --> 00:01:15,990
let me talk a little bit about the

31
00:01:15,990 --> 00:01:18,360
other stuff about what we're going to
cover today.

32
00:01:18,360 --> 00:01:21,850
We're going to talk about the post-course
survey, the TA program,

33
00:01:21,850 --> 00:01:24,130
and there will be an entire video on this
one.

34
00:01:24,130 --> 00:01:28,260
I urge you to look at it, you know.
And then other opportunities you'll see,

35
00:01:28,260 --> 00:01:32,310
and then some of the statistics that I'm
giving you every week, and I'll

36
00:01:32,310 --> 00:01:35,790
talk a little bit about the fact that this
is the final week, okay.

37
00:01:35,790 --> 00:01:41,490
So post-course survey, I think, you know,
it's very important that we

38
00:01:41,490 --> 00:01:45,290
understand exactly how you felt about the
class and the various topics.

39
00:01:45,290 --> 00:01:48,320
You know, if you want more details, less
details, if this is covered the same

40
00:01:48,320 --> 00:01:50,580
level where you want more information,
give us

41
00:01:50,580 --> 00:01:53,220
that feedback, you know, this is really
important.

42
00:01:53,220 --> 00:01:56,000
Same thing about the assignments, which
ones were too tough, which ones were

43
00:01:56,000 --> 00:02:00,580
too easy, you know, do you want more,
really or do you want less?

44
00:02:00,580 --> 00:02:04,050
you know, you know, basically give us as
much feedback as you can.

45
00:02:04,050 --> 00:02:06,500
Also once again you can post everything on
the forum, we

46
00:02:06,500 --> 00:02:09,800
actually read this all the time, okay, we
are really obsessed with

47
00:02:09,800 --> 00:02:12,630
this thing I think you notice, we read the
first, first thing

48
00:02:12,630 --> 00:02:17,550
in the morning, you know late, you know
last thing before sleeping.

49
00:02:17,550 --> 00:02:18,270
so put as many

50
00:02:18,270 --> 00:02:21,760
comments as you can, tell your stories and
and, you

51
00:02:21,760 --> 00:02:24,464
know, we can tell you that we read
everything, okay.

52
00:02:24,464 --> 00:02:29,156
so the TA program, okay so there will be
an entire video there so

53
00:02:29,156 --> 00:02:33,848
what we want to do is improve the class so
we want your help, okay?

54
00:02:33,848 --> 00:02:37,330
So, there are various ways you can help,
you know there are very, various

55
00:02:37,330 --> 00:02:41,110
forms of commitment that you know, you can
do and look at the video.

56
00:02:41,110 --> 00:02:43,320
We going to cover these things but it can
be as

57
00:02:43,320 --> 00:02:45,000
easy as just participating in the

58
00:02:45,000 --> 00:02:48,020
forum, answering questions, giving hints
to students.

59
00:02:48,020 --> 00:02:50,360
To something when you can really shape the
class and I

60
00:02:50,360 --> 00:02:52,930
will tell you in the other video what that
means, okay.

61
00:02:52,930 --> 00:02:55,280
But this is, you know, you can have a big
impact

62
00:02:55,280 --> 00:02:57,850
on the class and I'll cover that in the
other video, okay.

63
00:02:57,850 --> 00:03:00,260
So, but this is something we strongly
believe

64
00:03:00,260 --> 00:03:02,660
in, you know, the teach assistant programs
are

65
00:03:02,660 --> 00:03:05,480
making a huge difference in practice, so
you

66
00:03:05,480 --> 00:03:08,080
know, just watch the video please, okay,
good.

67
00:03:09,280 --> 00:03:10,270
yeah, right, okay.

68
00:03:11,290 --> 00:03:13,860
no opportunities you know, most of you
know

69
00:03:13,860 --> 00:03:16,320
that I'm professor here at The University
of Melbourne.

70
00:03:16,320 --> 00:03:18,560
I have another job actually which is

71
00:03:18,560 --> 00:03:21,484
leading the optimization group research
group at NICTA.

72
00:03:21,484 --> 00:03:27,580
It's sup /g, it's essentially NICTA is a
national ICT city center in Australia and

73
00:03:27,580 --> 00:03:32,190
is basically collaborating very very
closely with you

74
00:03:32,190 --> 00:03:34,320
know the main universities and the top
universities

75
00:03:34,320 --> 00:03:35,000
in Australia.

76
00:03:35,000 --> 00:03:38,130
Visit university of melbourne, the ANU,
and

77
00:03:38,130 --> 00:03:40,080
the university of new software in Sydney.

78
00:03:40,080 --> 00:03:42,930
So essentially this group is like a
national group

79
00:03:42,930 --> 00:03:46,034
of like 60 reseracher at this point five
professor.

80
00:03:46,034 --> 00:03:50,950
And these professor are like vampires
right, they like

81
00:03:50,950 --> 00:03:53,960
young blood and young blood for us well is
students.

82
00:03:53,960 --> 00:03:57,660
Okay, so we love students and we are
recruiting heavily students okay.

83
00:03:57,660 --> 00:03:59,500
So if you are interested okay,

84
00:03:59,500 --> 00:04:02,409
the Masters and PhD students, you, you,
you

85
00:04:02,409 --> 00:04:04,680
would be enrolled in one of these
universities and

86
00:04:04,680 --> 00:04:07,090
you would get you know for instance
scholarship

87
00:04:07,090 --> 00:04:09,440
From NICTA, if you get into the phD
program.

88
00:04:09,440 --> 00:04:13,320
So if you're interested in that, you know
you can email,you know Sandra, who is

89
00:04:13,320 --> 00:04:15,010
the coordinator of the group, really the

90
00:04:15,010 --> 00:04:18,560
brain of the group essentially for more
information.

91
00:04:18,560 --> 00:04:22,047
There are also optimization internship at
NICTA, for four ,six

92
00:04:22,047 --> 00:04:24,970
,12 months, make sure you want to do a
PHD,

93
00:04:24,970 --> 00:04:28,710
you can come and see what it means to do
research in such a group.

94
00:04:28,710 --> 00:04:31,390
And once again you can email us for more
details.

95
00:04:31,390 --> 00:04:35,810
And finally, some of you have been so good
that Phil Killby who has actually

96
00:04:35,810 --> 00:04:37,838
been leading the logistic part of the
group

97
00:04:37,838 --> 00:04:40,490
was like "woah these solutions are really
nice.

98
00:04:40,490 --> 00:04:42,680
I want these people to work for me" so if

99
00:04:42,680 --> 00:04:46,150
you are interested in logistics, like in
the VRP assignment, okay.

100
00:04:46,150 --> 00:04:47,990
So you can talk to you can talk to once

101
00:04:47,990 --> 00:04:50,030
again send an e-mail to Sandra and Phil
will look

102
00:04:50,030 --> 00:04:55,030
at your applications and decide if you,
you know, if you want to, if you can join

103
00:04:55,030 --> 00:05:00,160
this, this four month internship that he's
actually promoting, okay?

104
00:05:00,160 --> 00:05:03,820
So, once again these opportunities in, you
know if you are

105
00:05:03,820 --> 00:05:06,885
you know, if you want to pursue more
optimization with us.

106
00:05:06,885 --> 00:05:08,000
Okay?

107
00:05:08,000 --> 00:05:09,930
Now let my go back to the statistics now.

108
00:05:09,930 --> 00:05:13,290
This is the number of students active in
assignments, okay?

109
00:05:13,290 --> 00:05:15,310
So this is, you know, basically, you know,

110
00:05:15,310 --> 00:05:20,160
very stable at this point, okay?
slight decrease, okay?

111
00:05:20,160 --> 00:05:22,939
this is the total submissions graded,
okay?

112
00:05:22,939 --> 00:05:26,350
And so there is this very bizarre thing
here, right, so

113
00:05:26,350 --> 00:05:30,440
that's certainly, we have a lot more
submissions, so we will like.

114
00:05:30,440 --> 00:05:31,170
What's going on?

115
00:05:31,170 --> 00:05:34,360
Okay, and this is the submission per
active student, same thing.

116
00:05:34,360 --> 00:05:36,620
Okay, so what is happening?

117
00:05:36,620 --> 00:05:38,330
Okay, so this is the total number of

118
00:05:38,330 --> 00:05:40,600
submissions by people who are submitting
like crazy,

119
00:05:40,600 --> 00:05:43,960
okay, and so you see top, you know, this
is the second rank,

120
00:05:43,960 --> 00:05:46,450
this is the third rank, so about you know,
1500 for the second rank.

121
00:05:48,970 --> 00:05:52,280
And this is an interesting point, this is
the first ranked student.

122
00:05:52,280 --> 00:05:55,348
This student has submitted 190,000
assignments, okay,

123
00:05:55,348 --> 00:05:57,200
soultions, over the course of this class.

124
00:05:57,200 --> 00:05:58,350
Okay, and so this is

125
00:06:01,930 --> 00:06:07,133
the submission over time, okay, so this is
the beginning and then

126
00:06:07,133 --> 00:06:07,160
[SOUND]

127
00:06:07,160 --> 00:06:08,760
and this is a log scale right.

128
00:06:08,760 --> 00:06:12,520
So this is a, so this number, this
increase kind of crazy.

129
00:06:12,520 --> 00:06:14,395
Right?
So what happened?

130
00:06:14,395 --> 00:06:18,050
Okay, so what happened is that this
student actually

131
00:06:18,050 --> 00:06:21,090
had a very nice program sending solution
all the time,okay.

132
00:06:21,090 --> 00:06:23,520
Every time he would find a solution he
would send it.

133
00:06:23,520 --> 00:06:25,730
You can do that with the infer structure
that we have,

134
00:06:25,730 --> 00:06:28,292
probably it's not a good idea but still
you know, you know.

135
00:06:28,292 --> 00:06:31,811
This is what happened and we took a little
time to actually notice this.

136
00:06:31,811 --> 00:06:35,086
Okay, yep so this is the Participation

137
00:06:35,086 --> 00:06:39,170
per Assignment you have seen this graph
before.

138
00:06:39,170 --> 00:06:44,260
it's very nice you know like 850 for the
Warehouse Location okay, so this is a

139
00:06:44,260 --> 00:06:46,160
large number,if you can keep that number
for

140
00:06:46,160 --> 00:06:48,806
the last assignment that would be
terrific, okay?

141
00:06:48,806 --> 00:06:52,200
650 for the VRP so which is also good.

142
00:06:52,200 --> 00:06:54,990
Some of the Puzzle Challenge are growing
up, that's also good, okay,

143
00:06:54,990 --> 00:06:57,280
so you can get a little bit more points
for your distinction,

144
00:06:57,280 --> 00:06:58,470
see if you want to do that.

145
00:06:58,470 --> 00:07:02,520
Okay, so keep these number little bit up
and we'll be really, really, truly happy.

146
00:07:04,010 --> 00:07:06,230
one of the things that we have to tell you
is

147
00:07:06,230 --> 00:07:10,050
that on August 20, all the submissions
will stop counting toward your

148
00:07:10,050 --> 00:07:13,740
grades, so you have to submit before
August 20, that's the last

149
00:07:13,740 --> 00:07:16,350
day that which, you know, the submissions
will count for you grade.

150
00:07:16,350 --> 00:07:20,050
You can keep submitting, right, so but
that won't,

151
00:07:20,050 --> 00:07:22,310
that won't count on for your grade but you

152
00:07:22,310 --> 00:07:25,645
can see oh, you know if I had a little bit
more time I could have got a ten or okay.

153
00:07:25,645 --> 00:07:29,140
after that, after August 20 we'll take a
couple

154
00:07:29,140 --> 00:07:31,740
of days and generate all the certificates
for you guys.

155
00:07:32,980 --> 00:07:35,800
the course content remains open.
You can keep submitting.

156
00:07:35,800 --> 00:07:37,600
You can keep looking at everything, okay.

157
00:07:37,600 --> 00:07:40,148
But, your certificate won't be reissued,
okay.

158
00:07:40,148 --> 00:07:44,320
So August 20 is our deadline for getting a
certificate, okay?

159
00:07:44,320 --> 00:07:47,380
So you can cram a lot of work this week to
just you know

160
00:07:47,380 --> 00:07:48,580
get where you want to be.

161
00:07:49,970 --> 00:07:52,080
the next session probably in six or 12

162
00:07:52,080 --> 00:07:54,480
months so the course will remain open
until then.

163
00:07:54,480 --> 00:07:57,130
Once we go to the next session, you know
the current

164
00:07:57,130 --> 00:08:01,650
section will, will become, the current
session will become inaccessible, okay?

165
00:08:01,650 --> 00:08:03,850
So essentially we leave it open as much as
we

166
00:08:03,850 --> 00:08:06,236
can and at some point we transition to the
new one.

167
00:08:06,236 --> 00:08:09,350
Okay.
So thank you.

168
00:08:09,350 --> 00:08:11,260
You know, I think it was really a great
week.

169
00:08:11,260 --> 00:08:12,500
We'll have one more mail back

170
00:08:12,500 --> 00:08:14,070
probably last week.
next week.

171
00:08:14,070 --> 00:08:16,260
For actually summarizing everything.

172
00:08:16,260 --> 00:08:19,630
But you know, most of you are ready to go
to the next step in optimization.

173
00:08:19,630 --> 00:08:21,670
And once again, I love this graph you
know.

174
00:08:21,670 --> 00:08:22,710
Thank you, guys.
