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!

Its a very good course overall. Just felt that towards the end the material got too much to digest, might be a good idea to split the contents of weeks 3 and 4 into 3 or 4 weeks.

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.

Initially the accent was a little bit hard to understand, but after few minutes everything become crystal clear. Extremely useful course content.

Unfortunately the forums go inactive after the first few iterations of the course. One can still learn by doing the programming assignments

Nice introduction into string algorithms, even though Ukkonen's algorithm is missing and slides sometimes contain buggy pseudocode.

Course Content is good. Instructors are not that much active to give answers for the raised questions compared to earlier courses.

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

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

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

I have finished the specialization. This course is mostly useful though challenging.

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

very good and useful , but the last week algorithm is very complicated

Some of the algorithms are too hard to implement but worth the effort.

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

This was a good course. I mostly understood most of the content

Very focused on bioinformatics problems.

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.

I didn't think the lectures or slides in this course were clear and informative. It seems like they are going for the briefest, most efficient exposition possible. Which is not the same as making the material clear and understandable.
