This is a great class. I learned / re-learned a ton. The assignments were challenge and left a definite feel of accomplishment. The programming environment and automated grading system were excellent.
Incredible learning experience. Every programmer in industry should take this course if only to dispel the idea that with the advent of cloud computing exponential algorithms can still ruin your day!

Really enjoyed this course, the instructor, the explanations, and visuals are fantastic. The homeworks are challenging but the course provides great resources for visualization and testing and I learned a ton.

It's incredible that a college-level algorithms course this good is available for free. The lectures are good, the lecture slides are good, but the main value of the course is in doing the homework problems.

It's a very good course! I've learned Java and I had to think outside the box to get the most efficient solutions! It has many interesting and complex problems to solve.

excellent. exceptional way of teaching. the student needs to listen carefully all the words spoken, as the lecturer pinpoints every detail or touches them.

Challenging, but informative. I learned a lot and will think about programming algorithms and data structures much more carefully now.

Awesome course. The instructor is one of the best in the business. It gives you a proud feeling to be taught by someone who himself has contributed so much to the tech world in terms of Algorithm and Data structures. Though sometimes it does get a little frustrating as the topic is so hard. My only complain about this course is as the course is in java for people trying to implement the Algorithms in other languages like c++, python it gets a little hard to find the alternatives of language specific features in other languages so i wish some help was given on that regard. Overall great course. A big thanks to the instructor for making this course.

Good curriculum, but poor presentation.
These are the building blocks for physics engines and data structures, and most people won't have to implement this directly, but it's helpful to understand applications and limitations. Nearly all coding interviews will ask about these concepts as well, so this material has lots of value in finding a job. The explanations are detailed, and the visualizations for the various data-types are fairly good.
That said, there is room for improvement. After the first couple of assignments, I switched to auditing this course, because of all the issues.
- The content was not migrated very well, resulting in many/most exercises having disclaimers that they haven't been migrated yet, and others having links to resources that will need a few extra step to work. I think the materials might just be out of sync with the assignment descriptions, but they certainly didn't go smoothly for me.
- Practice problems have hints, but no answers. It's useful to think through, but you either know the answer, or you don't. You're probably better off just working through problems on codeforces.
- Long lecture format was from a traditional classroom. This works alright, but feels a bit bloated in comparison to other Coursera courses I've taken. The checkpoints are trivial, and added after production, so they didn't add much either.

Good course for a free one. Thank you for all of your great work. Somehow, the pace is too fast. Covering about 2 sections per week is by far too hard to read the book along with the class. There's no practice exercise to strengthen what you learn. The assignment is very hard and sometime don't directly implement the knowledge you learn in that week. Sometime the video sound is too quiet (but you can read the transcript when it happened.) The book is better in my opinion.

É ruim pq o curso é em ingles, e pelo menos a legenda deveria ser em português, e até a legenda ta em inglês também, pra quem está iniciando e não tem nenhum conhecimento em inglês é péssimo.

Python would be much better choice for this kind of course, Java is good but old school and archaic..

Too much detailed first assignment containing open-ended irrelevant tasks. Got bored.

This was an excellent course. I read along in in the Algorithms pt I book and the lectures were a great compliment to the book. The homeworks were quite challenging, but I thought they were all very fun topics and as others mentioned you really feel a great sense of accomplishment from finishing them.
I came into this class with no prior Java programming experience. The first and second homeworks were difficult for me as I was struggling with the language while trying to solve the problems. I think the way the course is structured (and to a greater extent the book) if you have a rudementry Java programming background (or experience with another languge--python for me) the basics of working with Java are described, and there is enough information and examples given to help you learn Java while you learning algorithms. Reading along with the course is a big committment (500 pages); a compromise that would be helpful for someone new to java is to read the fundimentals chapter (chapter 1), which is still 100 pages, but provides a solid enough introduction to Java (for someone with prior programmming experience).

Great course with appropriately challenging assignments! Clearly a lot of effort was put into designing them in such a way that the API and code-tester forces you to implement precisely the algorithm they're talking about, but you still have to write all the interesting code from scratch. Difficult, but a ton of test clients and other resources are provided to help you out. I felt really rewarded for each assignment completed.
I was taking this as a refresher (took Algorithms in college), and found the lectures much more interesting this time around. For example, the way Red-Black trees were explained as an implementation of 2-3 trees, made the algorithm much easier to understand than how I learned it before, which was that a red-black tree is a binary tree maintaining such-and-such invariant blah blah blah. As a result I retained more about how the algorithm works, and the invariant actually makes sense to me now.

This course is designed so well that it is the best as an introduction for algorithm beginners. It does not include any obscure maths formulas, but it has a lot of propositions and properties that build up the rigorous analysis framework, teaching us how to think systematically in terms of designing, analyzing and choosing algorithms. Leveraging Java, you can learn the algorithm implementations and applications by experiments. This approach makes algorithms learning very practical. The course also advocates for good programming style which is very important in software construction in the industry. This is assured by using some good tools such as FindBugs and so on. Last but not least, this course provides very rich learning materials, especially the high quality assignments with good auto-graders which provide us invaluable feedback, and high quality example source code and standard library.

I can't measure how important this course is to me. I am a graduate student in the field of Theory & Engineering of Control, which is actually a domain related half with theory and mathematics and half with engineering, coding and application. I have involved in some international competitions before, responsible for C++ coding. After I struggled to finish this course and all the assignments, however, I find that I have a better understanding of programming. What I should do is definitly not just finish the functions raised by a project, but to analyse my codes, to optimise them and maintain them as something can be reused. Also I got to know the fields of robot path planning (A* algorithm) and so on. I will take another part of this course in the next month cause it really takes my a lot of time, but there are something crutial to deal with. Thank all the friends I've met in the forum.

This course is great. The lecturer explains the ideas and illustrate them with animation crystal clearly. The effort put into the walk-through of the material can be clearly felt, which get the job done very well. The only thing that i felt somehow missing is the philosophy behind those algorithms, like what makes one algorithms faster than the other? Is it because slower algorithm does extra job than goal? The course might be more intriguing if that part can be covered to some extend.
The assignments really impressed me, especially how the design of auto-grader. This course can really be standalone without any instructor with this auto-grader. The assignments themselves are really useful in consolidating the covered material. Beside the design of the APIs give me a good lesson what a good encapsulation is and how convenient they could be, which is really useful experience.

I took this course with no prior experience in Java, and that was not a major roadblock to finish this course. The way Dr. Robert and Dr. Kevin have designed the assignment, it’s just fabulous. They provide the helper class – StdDraw, SET, and etc. All you need to do is think about applying the lectures from Dr Robert. The delivery of the lecture from Dr. Robert is very insightful, crisp, and to the point. I liked how Dr. Robert was excited while mentioning his Red-Black tree reference on a TV series (Spoiler Alert !!!), and how the order of complexity of various data structures are computed and compared. The assignments are designed to apply the concepts on real world problems. I would like to thank Dr. Robert, Dr. Kevin, and other mentors for sharing this well-organized and well-crafted course on Algorithms. I can’t wait to begin Algorithms Part II.

I highly recommend this course to anybody who is willing to learn about data structures and algorithms, understand in which situation which algorithm or data structure may be more suitable, how are these used in real life problems or even if you only want to practice them again. The lectures are very well structured, providing a lot of useful information and each week (except for the last one) requires to program a challenging* assessment (*depends on your algorithms and data structures knowledge and experience level). Even though all the material and programming assessments are in Java, it is should not be a problem to implement the same in any other programming language (except for you might miss the generics in some - requiring you to implement "same" data structures for different primitive/elementary data types).

Great content and the lectures were about as engaging as a video can be. The assignments were big enough to be challenging but not so big as to be daunting. For most intermediate level students I expect they will need to spend the time estimated. A passing grade on an assignment can be achieved without nailing down every detail, and I believe it does demonstrate an adequate grasp of the material.
I spent way too much time trying to max out my grades, but I enjoy programming and puzzles.
My only real complaint is that the IDE provided is a bit too nit picky. It's too concerned about spelling and flagged some of my defensive programming habits (initializing variables that really didn't need to be initialized at that time, for example). Annoying.
In summary, time well spent. Good course, looking forward to part II.

Excellent course covers basic algorithms and data structures, where theories are intuitively explained along with practical applications.
What impress me most is the programming assignments, which are both challenging and fun, helps strengthening my understanding of the topics and improve programming skills. It's very satisfying to improve my code and pass every correctness/memory/timing/bonus tests. I do wish there are more programming assignments.
However, I hope each topics are taught more in depth, I feel those text books contains way more contents than online courses, but reading those walls of texts are too dry and daunting compared to online learning and practicing. I understand that buiding a learning platform like this requires huge efforts, so this is just my wish.
Prof. Sedgewick is super great. This course is tough although there are only programming assignments in the coursera version. The videos can be viewed several times and we may catch up on ideas that we miss due to short-attention spans etc issues. I shudder to think of the days when we did not have video recordings... The assignments are graded by a machine using a very carefully designed method- they really take teaching seriously out there. It is all fine and such and did you know, they have a super cool java development kit and an algs package.. i haven't used java much for many many years but I enjoyed all the help that i got out of the course's JDK that offered loads of type checking etc. and you can install in linux or windows. Have fun at it, if you can.

Highly recommend to those wanting to learn from scratch or refresh their memory on data structures & algorithms. I recommend supplementing this course with the textbook version which features more details and homework questions in addition to the very well made programming assignments on this platform. If you enjoy this course, I would also highly suggest to check out the part 2 of this course. It is a little more challenging however I would debatably say the information in that part is very valuable as it includes many practical applications you would see anywhere. Cheers to Kevin Wayne, Robert Sedgwick and any other person who contributed to the development of these resources. It is greatly appreciated by many self-learning students including myself.
