1 00:00:00,210 --> 00:00:02,896 Okay. So, this is discrete optimization Mail 2 00:00:02,896 --> 00:00:05,650 Bag for Week 6. a couple of updates. 3 00:00:05,650 --> 00:00:09,940 Nothing major this week. so, we going to look at the graphs and, 4 00:00:09,940 --> 00:00:14,410 and, and talk a little bit about them. this is the number of students active in 5 00:00:14,410 --> 00:00:17,285 assignments. Little bit of a drop there. 6 00:00:17,285 --> 00:00:20,910 so, you know, this is leveling off. So, this is nice. 7 00:00:20,910 --> 00:00:25,695 this is the total number of submission graded that's increasing obviously. 8 00:00:25,695 --> 00:00:28,920 a little bit less than last week. Okay. 9 00:00:28,920 --> 00:00:31,620 And this is the number of submission per active students. 10 00:00:31,620 --> 00:00:33,680 We have a drop for the first time. Okay. 11 00:00:33,680 --> 00:00:36,465 Probably we made a mistake. We gave you, you know, kind of an 12 00:00:36,465 --> 00:00:40,000 extension, and you all took off on vacation on a nice beach, right? 13 00:00:40,000 --> 00:00:42,970 So that's what I'm hoping here. And we're going to go up next week again. 14 00:00:42,970 --> 00:00:46,360 Right? So, this, this are the numbers. 15 00:00:46,360 --> 00:00:50,185 The numbers are looking good. So, let's say TSP is above 1000 for 16 00:00:50,185 --> 00:00:52,790 everyone. Warehouse location is getting very 17 00:00:52,790 --> 00:00:55,090 healthy numbers like 600 and above. Okay. 18 00:00:55,090 --> 00:01:00,330 That's good. VRP, we are already looking at at 350, 19 00:01:00,330 --> 00:01:03,964 400. I think overall we have already something 20 00:01:03,964 --> 00:01:08,360 like 500 students who are really in, in good shape overall. 21 00:01:08,360 --> 00:01:10,460 So, this is kind of very nice. Okay. 22 00:01:10,460 --> 00:01:13,030 So these numbers are growing up, so this is good. 23 00:01:13,030 --> 00:01:14,960 This is the curve. Okay. 24 00:01:14,960 --> 00:01:19,620 not much happening at the hat, but what is happening at the tail is very nice. 25 00:01:19,620 --> 00:01:21,970 Okay. So, what is, what you, you know, what, 26 00:01:21,970 --> 00:01:25,160 what we wanted last week is happening, this tale is lifting. 27 00:01:25,160 --> 00:01:27,550 And when you look at this thing here right. 28 00:01:27,550 --> 00:01:29,870 So, this is, this is kind of thick. Okay. 29 00:01:29,870 --> 00:01:33,044 So, for the last assignments, we had a very substantial chunk. 30 00:01:33,044 --> 00:01:35,230 Okay. So, the number of assignments that have 31 00:01:35,230 --> 00:01:40,130 been completed compared to last week as, as kind of you know, same number last 32 00:01:40,130 --> 00:01:42,980 week, same number this week. So, this is moving up nicely. 33 00:01:42,980 --> 00:01:45,150 Okay. So, steady progress you know, very happy 34 00:01:45,150 --> 00:01:47,508 to see that. We need to lift it more, right. 35 00:01:47,508 --> 00:01:51,462 because we want to get as close as possible to this you know, black line at 36 00:01:51,462 --> 00:01:54,861 the top. common questions about certificate, there 37 00:01:54,861 --> 00:01:59,340 were a number of them in the last week. So, to get a regular certificate, you 38 00:01:59,340 --> 00:02:01,294 need 224 points. Okay. 39 00:02:01,294 --> 00:02:03,800 And anyway you like. You do whatever you want to get those 40 00:02:03,800 --> 00:02:09,100 points, and you get a certificate. Distinction is 300 points, and you can't 41 00:02:09,100 --> 00:02:11,890 get more than 30 points from the extra credit. 42 00:02:11,890 --> 00:02:17,766 And the reason we have that is that this guarantees that you'll devote 75% of ten. 43 00:02:17,766 --> 00:02:20,470 Okay? So, we don't want you to get all tense, 44 00:02:20,470 --> 00:02:22,560 but we'd like you know, a very large proportion. 45 00:02:22,560 --> 00:02:25,150 There are some of the assignments that we know are really difficult. 46 00:02:25,150 --> 00:02:29,384 You know, the largest TSP, or some of the really challenging warehouse location 47 00:02:29,384 --> 00:02:34,240 problems. so, so, essentially 75% is really, really 48 00:02:34,240 --> 00:02:35,920 outstanding in this class. Okay. 49 00:02:35,920 --> 00:02:39,159 so, there was steady progress on the assignment. 50 00:02:39,159 --> 00:02:43,181 Very good, very good work. I think you should also look at some of 51 00:02:43,181 --> 00:02:47,365 the traits that you know, we, we noticed this week on visualization. 52 00:02:47,365 --> 00:02:49,700 There are some beautiful visualization up there. 53 00:02:49,700 --> 00:02:51,900 this is something that we mentioned during the class. 54 00:02:51,900 --> 00:02:56,630 You know, it's also always very useful to actually visualize what is happening. 55 00:02:56,630 --> 00:03:00,380 When you visualize, you can identify bottle neck you know, I told you many 56 00:03:00,380 --> 00:03:02,910 times in this class. Sometimes, we you know, we've spent hours 57 00:03:02,910 --> 00:03:04,960 and hours looking at this screen trying to find patterns. 58 00:03:04,960 --> 00:03:08,360 What is happening. Why are the, why are the algorithm 59 00:03:08,360 --> 00:03:10,610 working that way? You know, when you visualize, you see 60 00:03:10,610 --> 00:03:12,255 these things. And you know, if you look at these 61 00:03:12,255 --> 00:03:15,710 thread/g, people have done a really good work in visualizing some of the results. 62 00:03:15,710 --> 00:03:17,810 And this is something that you can think about. 63 00:03:17,810 --> 00:03:21,400 You know, when you are starting doing an assignment, just try the visualization at 64 00:03:21,400 --> 00:03:23,950 the same time. It doesn't take very long, in general, 65 00:03:23,950 --> 00:03:28,040 but it, it really informs you about what the algorithm is doing. 66 00:03:28,040 --> 00:03:29,540 Okay. So, keep the good work. 67 00:03:29,540 --> 00:03:33,070 I'll see you next, next week. So, this is the final stretch. 68 00:03:33,070 --> 00:03:35,690 Right? You can look at the assignments again. 69 00:03:35,690 --> 00:03:38,940 revise all of them. I saw, I saw on the forum that some of 70 00:03:38,940 --> 00:03:41,760 you were actually doing that. Keep doing that you know, that can make a 71 00:03:41,760 --> 00:03:43,990 big difference in the end. And now, you can look at them in a more 72 00:03:43,990 --> 00:03:45,320 relaxed fashion as well. Okay. 73 00:03:45,320 --> 00:03:47,270 See you next week guys, keep the good work.
