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.

I would like to give this course worse than a 1 star. The course explanations are very poor. The explanations drag on and make no sense. I had to go to outside sources to make sense of what the videos were discussing, which I felt like defeats the purpose. Why am I paying for something when I have to use other sources to better explain. I would never recommend this course to anyone. Listening to these teachers explain each subject poorly was killing me. I like to learn through examples but what they provide just makes it more confusing and hard to follow. Each instructor got worse and worse! The videos were so hard to watch and the accents made it even more worse! I feel robbed from taking this course. I should have asked for my refund within the first week, but I felt since I was paying, I would stick it out a little longer. You will get a better explanation if you take each subject and youtube the videos on each subject. Very useless course. Hated every week of this course and I wouldn't dare to continue with the full specialization program. It's very sad to hear that this course gets recommended a lot, but it missed it's mark completely.

If you want to learn more about both theoretical and practical computer science, do this specialization. I'm completely sold on this specialization after one week. The instructors are extremely helpful and have a high level of clarity both in the videos, and on the forums. The language semi-agnosticism is excellent! The forums are active and friendly! You will hit the ground learning right away with this specialization!
This course has so far motivated me immensely to delve further in to my software engineering education. I did not get a Bachelor's degree in Computer Science, just an Associate's. Though I work in the industry, I wanted to do programming competitions and personal projects to make up for the lack of experience with the ideas and implementation of algorithms and their data structures.
This course has jump-started my journey beyond my current abilities, and I believe it will do the same for you. If you're even remotely thinking you would be interested in taking these courses, do!

I must confess I was a bit hesitant to start this specialization. But after 3 weeks in, I am very happy that I started with this specialization. The course has the right pace and instructors have very nicely divided the videos in shorter logical entities which are easy to understand. I love the exercises. All the other exercises in other courses that I have taken for coursera provide you with a lot of code already done and you just have to write a very small piece of code to complete the assignments, but not in this one. We need to write the whole assignment on our own, right from choosing the appropriate data structure and algorithm design. They sure have a starter code but I only look at them once I have some solution, in order to do a check of my code design as well.
I must say, this is an awesome course. Great work guys putting this together.

I'm still in week 2, but so far I'm loving it. It's far more interesting and engaging than I thought it would be, and not as hard as I thought it would be. It requires some programming experience (a few months of practice and maybe a more advanced understanding of your programming language of choice will do) and the "mathy" way some algorithms are explained can be a little scary for who hasn't a good maths background (like me!) but don't let it scare you away. Everything is actually much simpler than it looks like and the only real demand is some patience and a willingness to find new ways to solve problems. Every time you an assignment right, you feel like you "leveled up" your problem solving skills a little bit. Totally worth it. Looking forward to the rest of the specialization.

The content taught is the lecture is not sufficient to pass the practical assignments.
I request you to use a dark background on slides.
The working of the pseudocode is not clearly explained with examples. I find difficulty in understanding the working of the pseudocode on examples.

I was able to complete the entire course, however I do see a LOT of room for improvement.
The transcript has many incorrect words. If the lecturers are reading off a script, then it doesn't seem like it as many of them accidentally mess up their words. This can confuse novice learners. The slides appear to be the critical portion of the course, with the lecturers explaining what is on the slides and little more.
I used Python for this course. Most novice learners will be using IDLE and not touch anything related to PyCharm (or, like me, already have PyCharm Community installed rather than PyCharm EDU and would not like to experience the annoyance of having to install yet another PyCharm). Much of the input for the autograder relies on sys.stdin, which would read files stored on the server. However, for client testing on IDLE, this needs to be replaced with an input() function so that you could test for bugs. Novice learners may not know how to do this and will experience frustration when their input isn't accepted.
Many of the lecturers are probably not native English speakers, and that is not a problem. Personally, I can easily understand what they were saying. However, other people who do not have experience listening to those with more pronounced accents may have difficulty understanding the lecturers, and the accents will obviously not help when it comes to understanding new and difficult concepts.
The usage of pseudocode is understandable, as people will be coding in multiple languages. However, I would recommend that the pseudocode use names such as "max_array" and "min_array" rather than simply "M" and "m" with the lecturer having to remind us which is which. Same for indexes, don't use "i" and "j", try to use "row" and "column." This will teach us good coding habits (use descriptive names) while making explanations clearer.
Of all the courses, the "worst" part of the course is likely the weeks involving Dynamic Programming. Dynamic Programming is a very difficult but also very important. Most novices will have never seen the concept of Dynamic Programming, so the need for a clear lecturer and in-depth explanations becomes much more important. However, the explanations are rushed (which is not good as 2D arrays are being used more and are much less intuitive). Also, I'm surprised they didn't talk about shortest paths/number of paths, which would help people get used to 2D arrays.
Finally: Unless you are already experienced in these algorithmic concepts, the time you need to complete this course is probably much greater than the course's estimates. Be prepared to dedicate yourself.

If one has taken the Algorithms 1 and 2 course by Profs. Sedgewick and Wayne, this course will be a disappointment and waste of time.

This Course is really very helpful in understanding the basic algorithms and various efficient problem solving technique. Week assignments are very good and helped me evolve my skills in implementing solutions and to consider every possible kind of instances for a problem. I loved the lectures and the way professors explain things and touch every aspect of the topic. I enjoyed this course very much and have learnt much more than what I thought I required. I am really very thankful and grateful to the professors and the Coursera. Thank You Very Very much. :)

I always feared coding problems on divide and conquer and dynamic programming. The way this course gradually took me from easy stuffs to advanced was awesome. After doing the course, I feel confident on coding difficult problems. I also appreciate the granularity of topic that this course covers. I took many courses but nowhere until now, I have seen courses that cover how to test and debug your code. Great Course and much take course in case one wants to get good at competitive programming. Good Job teachers. Your efforts are appreciated.

Really nice course that get's you started to the world of algorithms. It has a balanced progression and introduction to basic concepts, but highly recommend to do all the optional assignments since they help absorb all the presented material to the fullest extent. But to solidify the knowledge gained, I would recommend to solve more problems on the introduced concepts since I feel this course falls short in number of diverse problem statements to be able to think on how to apply the concepts in different scenarios.

I recommand for everybody. Teachers explain all from the basic level, and you shouldn't be afraid, you will understand all algorithms from this course. I like this course and this specialization very much
Для русского язычного населения тоже очень рекомендую, английский базового уровня, преподаватели с хорошим произношением, просто огонь. Сам курс вам тоже очень понравится. Очень нравится, что сначала дают теорию, а потом сразу к этой теории задачи, чтобы вы всё смогли отработать
Thanks for this course

Great course with the thoroughly prepared exercices and detailed video explanations for each topic. Covers a wide range of fundamental alogorithmic technicues that are good to learn for everyone who wants to become a better software engeener or just to improve programming skills. The course passing grade is pretty soft. It is enough to attentively watch the video lectures and carefully implement algorithms covered there to pass the course, however some advanced problems are really challenging.

A very thorough introduction to the core concepts of Algorithm design, including sorting, binary search, greedy algorithms and dynamic programming. The assignment are tough with the last few definitely challenging, you will spend quite a bit of time implementing them if you are new to programming in general but there is enough help on the site (and the internet) to help you figure things out. Working through the problems is essential to getting the most out of the course.

This is a really well planned course. I was doing this course and auditing my on-campus course too, initially. But, I soon realised that this is what I need. It has a perfect balance of mathematical rigour and practical programming. The programming challenges sometimes felt tough, but since ample time is given to solve, I could make it in the end. Thanks to the instructors for teaching students across the globe. Knowledge is a debt that can never be repaid! Thanks

I think this is the best algorithms course I've taken so far. It wasn't too hard, but if you wanted some challenge there's always the advanced problems. Speaking of the problems, I highly recommend that you solve all the programming assignments, including the advanced questions. Even if you can't solve it on your own, search up how to do it; just don't give up. Passing is easy, but to get the most of the course you need to finish all the programming assignments.

This course is undoubtedly valuable. I definitely learned some skills that I am glad to have had real practice in. That said, you really have to do the majority of the work yourself. I have the CLRS book, the Dasgupta, and have watched a host of supplemental videos on YouTube, MIT OCW. This course is not an "all-in-one" solution. It's sorta like a high-level guide and tough challenges and a grader. The videos are decent, but by Mithras' eyelash they can be incredibly boring. Furthermore they don't take advantage of the video medium properly. The visual aids are really sub-par.
Also, be ready to repeat the course. I signed up in the late-summer and it took me all Fall. While I certainly was busy, the lack of support, the digging I had to do, the note-taking I had to do, the processing I had to do on my own all added a lot of work. I'm curious as to whether I've gotten better at "taking Coursera Classes" and will have better luck next class. I'm pessimistic.

the material are great so much information and it is the first from the hole specialization
but! the explanation is so weak doesn't match at all with this big data
the pseudocode is so distracting and hard to read
i always get lost and i don't know is it an array in the code or variable and what does he want to do with it
the pseudocode should be just a normal english code saying what to do
not an understandable signs :\
i am really sad that i couldn't get benefits from this amount of knowledge

Def a useful skills to have when starting to interview for jobs. This is a hard course to teach to begin with. I found the lectures really boring, too long, hard to understand and just not really motivated well. I think the homework problem are good, but they are very time consuming. You need to use various methods to find edges cases and though that might be a good skill to have as well, it's just too much to get done in one week and somewhat frustrating when you're only stuck in one test case. I think this could be an excellent course with a few modification on the slides and adding more motivations and making shorter homework problems that focuses on the main part of the material for that as oppose to things we've already covered in the previous week. At the moment, I don't think I'll continue this specialization the way it's designed.

I tried to have this specialization and canceled before the 7-days free because the explanation is so poor by the teacher.
When seeing about Big-O notation is possible to see a poor explanation and most of the time you need to access a content to other source as KhanAcademy. It's not acceptable.

This is one of the best courses i have taken. The way these instructors come up with a problem and explain why existing techniques are not that helpful, and intuitively explaining why new method/technique would suit the problem. everything about teaching was simple yet amazing.
Moreover the assignments are also quite challenging, so they will for sure give you tough time and make you put in more effort which in turn sharpen your strengths on the concepts.

This is a great introduction to a more formal approach to algorithms and I look forward to the rest of the courses in the specialization. The dynamic programming week was somewhat more difficult than the other weeks, but I think that could be remedied with more visualizations during the lectures.
If you're lacking in any basic maths skills, I would recommend running through Khan academy first. Functional notation and series would be especially useful.

This course gave an insight in the world of algorithms and taught me a number of different approaches for solving algorithmic problems (stress testing, for example). I discovered the fact that my programs didn't worked properly in all cases (I was pretty confident that they did) and realized that there are really wise solutions for many computation problems. Lastly, all course materials were explained in detail, so there were no unclear moments.
