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.

Cool course. Thank you! One suggestion about your book (Learning Algorithms Through Programming and Puzzle Solving): could you add some theory which would serve as a brief reminder before problems?

I'm giving 3 stars out of respect for the hard work the instructors, Coursera community and course mentors put together to make this course happen, but the quality of the course is at most 1-2 stars. I finished 100% of the assignments even though half of that was required to pass the course, and I have a few concerns about this course:
1 - Poor Use of Pseudo Codes. While Pseudo codes are perfectly fine and sometimes extremely helpful, none of the Pseudo codes in this course were intuitive and can be efficiently translated into real codes. First of all, variable names are confusing and do not tell you what this symbol holds at the first glance, just like how the whole course was taught in a mathematical way rather than programming way, variable names are all like i, j, s, t, l .... when we could have made them into something meaningful and readable.
2 - Since only Pseudo codes were given, it's hard for newer students to learn how a working algorithm actually looks like and how it runs at each step. I feel that either you already know how to do it, or you can't come up with one at all before debugging for hours. So it is more important to show something that actually works from the beginning, then students can imitate -> improvise -> create. Again the Pseudo codes are terrible examples.
3 - DP sections were badly explained, really really bad ........ any of the YouTube videos and GeeksforGeeks explanations are 10X clearer and more intuitive. I feel like the instructors just wanted to teach the math instead of how to program. But the math isn't any difficult to understand, the key is to convert ideas into codes, and this part was completely ignored.

I agree with some of the reviews here. It's fantastic at the beginning of the course. Towards the end, unfortunately the professor's accent is heavy and sometimes difficult to understand. The subtitles don't help either because they were auto-generated. My brain had to take extra cognitive workload to decipher what was actually said before trying to understand the materials on the slides and everything else. I also didn't like the way index 0 and 1 is mixed in different lectures. Why shouldn't we stay consistent in pseudocode using index starting with either 0 or 1? The slides are confusing regarding this matter especially when you translate algorithms into code.
Nonetheless, I liked the assignments overall. The course's instructors included some of very interesting problems and indeed helped understand the lessons better. I also liked the course structure and the carefully prepared slides.

If you're a self-taught coder, then you should take this course. It teaches you how to construct efficient and working algorithm. It's getting harder when it comes to Divide-and-Conquer because it is hard to imagine and also in the Dynamic Programming because the lecturer does not start with the definition of DP itself. The 'language' used by the lecturers in some sense is hard to be understood. Also, the mentors and people in the forum is not so active. I already asked several questions in the forum, but until now there's no responses.
The amazing thing about this course is it is the PROGRAMMING ASSIGNMENT. It'll force you to find external references. You have to spend more time than the estimated time from Coursera.

Course is overall great but some cons as per me:
1) The instructor`s accent was hard to catch sometimes.
2) I know Discussion forums are for students and testing solutions is one of the most important part but after trying for so much time, there are times when one cant catch the failed test case and neither other students(atleast those who posted). In such cases there is practically no other way than to leave that assignment as it is. I just think Ta`s should be more involved in forums and should give some insights when some student has failed after so many attempts. As there are still posts with same doubts as mine which are unanswered from 2-3 months.In short forums should be as great as udemy`s forums.

The problem sets are great and probably worth the price, but the lectures become very hard to follow after week 3 and the discussion forums are very disorganized - it's hard to find useful information. Some of the lectures have slides available, some don't; some of the lectures have somewhat-useful subtitles/transcripts, others have incomprehensible garbled messes (I don't know if they're machine-generated or just transcribed by someone with no understanding of the material/vocabulary - logarithm != algorithm!).
I really like the problem sets, but some of the lectures are pretty rough, just a guy talking in front of some pseudocode for 10 minutes. The instructors seem friendly and engaging, though.

I learned a whole lot, but the course wasn't easy, chiefly because of reasons beyond the subject matter. Some lectures were really hard to follow. I get that English is not some of these guys' native language (it's not mine either), so they can't make everything as information-dense as native speakers, but there were a number of confusing parts, mostly in the pseudo code or the general explanation of the algorithms, especially in the Dynamic Programming module.
It was an OK experience and I learned quite a bit, but I'll probably be dropping this specialization in favor of another one that tackles similar subject matter.

Not bad overview of greedy, d&c and dynamic algorithms however the examples within the lectures and the way they were presented was not often clear. I found much better ways of explaining these elsewhere online with more cohesive and clearly connected thought processes. I'm new to this and maybe it's just the way i think and my lack of background but the way subproblems were integrated back into main problem were either glossed over or considered so "obvious" that they weren't worth mentioning.

I really had a hard time understanding Dynamic Programming. I recoomend to remove this topic and focus more on solidifying foundations so that students can be more prepared for moving through the whole Algorithm Courses. I never heard of this topic before and the lecturer ommited many steps when explaining the Edit Distance. I was forced to look for other resources like Open Courseware Algorithms course, and this is how could understand what was dynamic programming easily. Hope this helps!

Overall is good course with many exercises, forum is supportive, however mentors/instructors never answered my questions (i guessed they bothered only with the very first session when course was launched) Language is sometimes overly complicated and hard to grasp the main principles of the algorithm (e.g. dynamic programming week 5) I watched youtube to understand same ideas but explained in much simpler way.

The learning curve becomes very steep towards the end of the course. Also sometimes it's difficult to understand what the instructor is speaking and the transcripts aren't very good. The assignments need to have some more problems in the easier category as it's only by doing many problems one gets hold of a concept. Although the difficult problems help , but they tend to be more demotivating

The course is good overall but I worry that for the non technically oriented the examples are very terse and could use more visual linking and vocal guidance on what the variables in the examples actually are, and the thinking behind the code presented. There are also a ton of implementation based gotchas depending on the language that a green developer is likely to get hung up on.

The programming assignments are top-notch. Really tests your algorithmic skills. That being said, I didn't find the instructors explaining the algorithms clearly. They were vague in that aspect. They would just tell what is in the slide and would not make efforts to clarify the tedious parts of the algorithm

The content is very good. But I don't understand the material well in weeks 4 and 5. Maybe you need to emphasize a bit on it, and put a little bit extra effort in the slides to make the algorithms more intuitive and more understandable. Also, maybe split the idea behind an algorithm into more than one video.

I like the fact that we get to solve many problems on our own every week but in all the lectures, instructors explain things only vocally and it's also very fast paced. It was really difficult to follow compared with lectures where instructors write on the white board while they are explaining.

I had already done "Algorithms: Design and Analysis Part 1", so this course was not as good as that one.
This course had lot of programming questions, which I find very good to have for any course. I just hope next courses of the specialization will be beneficial for my career.
