Very good course. String algorithms are very important in day today life and one should really know how to solve command problems related to it. This course have described everything so well.

Very well put together course. Challenging but understandable. I highly recommend you stick out. If you get stuck check the forums there's lots of helpful things there. Time well spent!

The programming assignment should be more clean with detailed instruction in each code file.

Still stuck at Problem 5 of Week 1, had to left this problem undone.
Wondering if the mentors or professors can send those who completed the course the standard/reference solution/program via Email???

It would be nice if you could deliver the problem's solutions after the course ended. I ran out of ideas for the BetterBWMatching problem and i couldn't overcome the time issues.

A good course giving insight into how important string algorithms are for not only to computer science community but also its use in other disciplines like bioinformatics etc.

too complex, and I don't think in the future work I will apply these.

Quite an interesting and well-organised course, giving a detailed overview of the pattern matching problem and solutions for it (on the other hand, if you are expecting to see a wide variety of string problems, the course title is misleading).
Assignments and quizes are also likeable (although the pseudocodes in the slides and the code skeletons for the solutions contain quite a number of mistakes).

Overall, I shall give the course 5 stars, however, I am not very satisfied with the first two weeks. The slides are incomplete and listening to the video is a headache. The professor just confused me and I cannot follow since the material is not well taught. The first week's assignment is so difficult and it spends me several days instead of declared three hours (although almost none of assignments could be done in three hours). The 2nd weeks however, the assignment is so simple. But the most annoying part is still the way it is taught in the first two weeks which almost make me quit this course.

Some tasks was hard to understand and solve, but it in general it was good.

Spent a lot of time trying to solve the last advanced task in the last assignment, but never solved it. I'm not sure if there is a mistake in slides or my misunderstanding, but it was really hard. Thanks to all the instructors.

Very good, although the material in last week is way harder and rushed than the rest.

i enjoyed the course. The course lecture for week 3 and week 4 can do better with presentations. One looses focus very quickly when the instructor keeps speaking, but the material itself is not hard. I had refer to outside material to understand the lecture and had to spend time. I would recommend Ben Langmeade lectures for to get grip on BWT and excellent lecture on KMP and Maben Meyers algorithm intro by Robert Sedgwick.

It's a very thought provoking course. I am into job for last 16 years and after getting into leadership role, hardly got into solving problems personally. This refreshed my passion and I connected well. I could not spend as much time as needed but overall I enjoyed the learning and the problem assignment. Worth trying!!

Really great course covering material that is not usually covered in algorithms courses, which is fantastic! The only feedback I have is that in some of the videos (the later ones on Burrows Wheeler), the material is covered extremely fast. I had to look at a lot of external resources because it was too fast.
As for the programming assignments and other material, absolutely brilliant. I learnt a lot and I am planning to do another course in the specialization.

I think it would be more helpful to trade BWT to more practical Polynomial Hashing tricks. Otherwise good course

Great course with great content.
However the video explanations could be better. It is hard to truly understand the concept through the videos. I just watched the videos to serve as a "roadmap" and to really understand the topics you'd have to read the chapters from the books listed in their reading section.
Still a good course overall and homework assignments are great.

The lectures are excellent. However, with reference to the logistics, it would really make sense provide test cases that are run. At least, the test cases should be made available once the student completes the assignment. By looking at the test cases, students can understand better with reference to developing better test cases in the future.

The lecture was very abstract and difficult. I could pass the course somehow by writing the code presented in the lecture, but I must say I understand less than the half of the course contents.
Responding to question from the instructor, I clarify the comments above.
I found the whole lecture difficult. This may be because the subject is not something I have even thought about. It was difficult to understand the difference and importance of key concepts such as trie, suffix, class, etc. Overall, I learned that the tricks somehow work, but my comprehension was not as deep as I can think about the extension or applications. I guess more examples or providing intuition would help me to digest the material.

My least favorite course in the specialization. The lectures are harder to follow, and are actually all about bioinformatics algorithms, which wasn't clear from the course description. Thankfully, as with the graphs course, Michael Levin wades in to save the day for the last couple of weeks. His lectures are really well structured, intuitive and clear.
