課程概述

World and internet is full of textual information. We search for information using textual queries, we read websites, books, e-mails. All those are strings from the point of view of computer science. To make sense of all that information and make search efficient, search engines use many string algorithms. Moreover, the emerging field of personalized medicine uses many search algorithms to find disease-causing mutations in the human genome....

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.

course content was great but i personally feels some difficulties in the implementation part so the course is meant to be more implementation oriented . thank you for the wondorful course

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.

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).

I have only one feedback: the relation between subsequent weeks are not clear. It feels like I am learning one technique in week 3, and then another in week 4, but why is the technique in week 4 necessary? What are the differences in terms of functionality, between the various techniques? I think these points are not explained quite clearly.

Great course though, thank you very much!

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.

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!!

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.

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???

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

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

An awesome course, though a bit more rushed than the other ones. Luckily with the notes, the assignments can be passed.

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.

It was good. But its assignment is easy compared to before lecture things.

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.
