À propos du cours

The course covers basic algorithmic techniques and ideas for computational problems arising frequently in practical applications: sorting and searching, divide and conquer, greedy algorithms, dynamic programming. We will learn a lot of theory: how to sort data and how it helps for searching; how to break a large problem into pieces and solve them recursively; when it makes sense to proceed greedily; how dynamic programming is used in genomic studies. You will practice solving computational problems, designing new algorithms, and implementing solutions efficiently (so that they run in less than a second)....

I liked the fact that the algorithms are not just the introductory searching and sorting algorithms. The assignments are fairly difficult (I have decent scripting experience), but not impossibly so.

good course, I like the fact you can use a lot of languages for you programming exercises, the content is really helpful, I would like to have more indications from the grading system to save time.

An okay course, a bit less implementative.

Even though this course covers a lot fundamentals for introduction to algorithm, the course itself is not designed as good as I expected. For starters, the weekly problem designs aren't very good. Some problem statements are ambiguous and not very clear unless you read more than one time or take a closer look at the examples. Often, the input format/arguments are designed to take redundant info. Some problem even has more than one possible correct outputs, which is just confusing for learning purpose.

In terms of lecture videos, it's good that there are some classic algorithm problems being demonstrated in the video, however the linkage between how to express a problem in mathematical languages is poorly explained. For example, in the lecture of edit distance, the realization of the matrix was not well explained at all. I personally appreciate a lot of the thorough proving steps introduced in the lectures, however I personally think the proofs are often not well explained to the audience (I also understand that it's more difficult to explain proving steps). Considering the large variety of audience, I would recommend the instructors separate the comprehensive more in-depth knowledge into optional videos, in this way the audiences could decide if they want to spend time in optional videos or not based on their own needs, meanwhile the instructors could spend a little bit more time to explain the difficult concepts better. Overall, I know that talking and analyzing algorithms can be kinda of boring and challenging, but I wish the course videos could be stated in a more interesting and intriguing way.

The course starts very promising, but it gets worse week after week, culminating on a barely understandable week about dynamic programming. That’s when I gave up and decided to write this review instead, with just one assignment missing to complete the course.

Some of the teachers aren’t native english speakers, which is fine, but their english is very hard to understand. I found myself having to watch some portions of the videos over and over again in order to understand what was being said. I tried reading the transcripts instead, but the they’re even worse! It seems that they were automatically generated from the videos, thus suffering with the poor pronunciation.

The teachers use mathematical sophistication that feels unnecessary, but to be fair, they do mention it on the FAQ as part of the necessary background. However, even though it’s an online course, they barely use any teaching method besides very raw slides, some dry mathematical proofs and someone speaking about the content. The only resources offered to help learning are a few open source visualizations. I expected much more.

The only good aspect from this course are the assignment checkers, which allow you to write your solutions in multiple languages.

I deeply regret the money and time I spent on this course.

The course has multiple limitations and can improve a lot more. Two main issues I faced were these:Dynamic programming part one lectures were very poor and hard to understand as a result of which I had to view external sources to understand the topicSecondly, the idea of not showing test cases is a bit strange as understanding the failing test cases do not really come in the way of understanding algorithm, it simply makes the questions much harder and tedious to solve. This completely eliminates the purpose of the course and wastes the time of most students. I am a bit disappointed with this course and didn't see it as value for money.

Update: As I proceed to wk 5, I know why there are some complaint on Dynamic programming,

Reduced to 2 stars. Lectures are totally useless for the assignment,

The course is really good until week 4 when it deteriorates very quick. No matter how many times I re-watch the lecture, I can't understand much. I ended up using wikipedia for the quiz instead :P

I can't use much of the course forum since there are too many posts there and it keep crashing my chrome.

This course gets my 3 stars from the first 3 weeks alone, otherwise it gonna be 0-2 stars.

I started the course to gain knowledge in algorithms but I am disappointed. Of course there are lots of assignments to do which kind of upgrade your skills. But I am disappointed with the way of explanation. The explanations are just like reading scripts. Also, they don't give the problem statement properly. I assignments, you would find the title of the problem but not the actual problem statement.

The instructors are very knowledgeable but I don't think their explanations are right up to the mark, at least not for me.

Course started out great but as time went on the quality kept dropping. Week 3 is where it started to go bad for me. The instructor kept jumbling words up and explanation was really poor. Later weeks most of the algorithms weren't properly explained and you have to actually google stuff and read and learn everything pretty much independently from elsewhere if you want to code up the problems. The blind test cases were really weird because you have no clue what went wrong and where it went wrong.

These two stars go to the instructor in week 1. I left the course after week 3 because I couldn't tolerate the accents of the instructors. I got frustrated starting from week 2 where I have to reread the subtitles to understand the material. Please let someone who can speak English fluently teach the course, please. The course goes kinds of fast, this is first course of the Specialization and it quickly jumps to Greedy algorithm, really? In general Algorithm course, it is usually taught late.

The videos and explanations are very poor. Most of the time the instructors are reading off a script, and everything feels fake. By reading off a script they are forced to "hand-wave" and do not explain concepts covered completely.

The only thing I liked about this course were the problem sets, which were interesting to do. Will not buy rest of specialization, feels like this is just a cash cow for UCSD.
