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!

Bardzo dobrze omówione zagadnienia (przykłady, ilustracje oraz animacje, wszystko z komentarzem). Dodatkowy plus za dobre przykłady implementacji w kodzie oraz za bardzo fajne biblioteki pozwalające na ilustrowanie działania kodu - świetna sprawa móc zobaczyć na ekranie co się dzieje. Ciekawe zadania praktyczne - uwaga, trzeba się momentami nagłowić nad prawidłowym rozwiązaniem. Mały minus za opisy zadań testowych oraz feedback czemu testy nie przechodzą - bez szerszego opisu testu czasem ciężko jest znaleźć błąd w kodzie. Polecam ten kurs.

It was certainly challenging. The programming exercises were hard and took me multiple attempts to get them right. But they were rewarding.

The interview questions were optional and I did not get much out of them. Some of the weeks had a slightly odd structure where the programming assignment was in the middle of the lectures, meaning you would have to complete the lectures after the programming assignment, which I felt was a bit odd.

Overall though, good course, and very challenging if you aren't a good java programmer.

Good: The instructor is reputable, and knows the stuff. Explanations are okay.

Could Be Improved: (1) Explanation for some topics is not enough, or does not cover the material well enough to finish the assignment. (2). Assignment grader checks for internal implementation of the solution rather than what can be accessed via the public API. I spent quite a lot of time with KdTrees exercise.

(3). Videos and assignments take much longer than officially recommended.

At 1st this course seems easy but as you start working through it, you wouldn't be able to do any assignment without a proper understanding of other data structures and algorithms, which aren't mentioned in the content. Every week you would be introduced to a small, basic algorithm and/or data structure and by the end of the week, you would be doing a tough assignment, which literally boosts your confidence... Highly recommended for software engineers.

I really liked the videos and the lecture slides. I think the assignments were really good as well, but had the feeling sometimes small but important informations were missing or not placed well enough. I read the description for the 8puzzle half a dozen times, but that this is not actually solving the task in the optimal amount of moves but rather in some arbitrary amount of moves (we just output the optimal moves) somehow escaped my attention.

Si no estas habituado a programar con JAVA se invierte bastante más tiempo del indicado. Las tareas pueden llegar a ser bastante pesadas y la información proporcionada tras la batería de test puede no ser suficiente para depurar tu programa. Me ha resultado más difícil de lo esperado, pero sin duda alguna merece la pena para refrescar conceptos vistos en la universidad y sus aplicaciones

Very great course to understand the algorithm and usage of data structure in java from bottom to up! In lecture, the professor talks about each concept step by step and discuss the implementations in detail. Through the assignment, I also can know practical usage of different java data structure. The assignment is challenging and a bit hard but makes me feel motivated to complete it.

The assignments are very challenging but it will help you understand not only the concepts but also the real implementation of the algorithms. Although I don't like the pace of the professor in class and sometimes it made me feel distracted..., I still appreciate the whole course and recommend it to anyone who is interested in learning Algorithms.

Great course for students who are familiar with basic data structures and good at Java programming. I am thankful to the Teaching team who responded to my queries. Highly intensive programming assignments have a steep learning curve. Ideal for learners who can spend time and have patience to continuously develop correct solutions.

first task seamed pretty challenging to me, but later ones were just fine.

very nice thing is that you don't have to watch videos to study. it's just impossible to listen 100 times something difficult, unlike text - you just see all the material and have enough agility to understand material.

4/5 because practise quiz is not tested.

Course is quite nice. I found the assignments challenging. As constructive feedback I would recommend to highlight the most important key concepts for each week, similar to the summary runtime table but with key concepts of each algorithm in quick-card that can be used and recalled during real world programing work environment.

Course is very relevant, lectures are excellent (nicely explained), topic flow is good. Assignment levels are also good and quite par with the expectation. Only issue is that non-java developers or newbie's would find quite difficult to complete the assignments, which would decrease their morale for continuing the course.

I really learnt a lot about algorithms and data structures, Its my first time reading about this topic,

and it was a great experience,Prof. Robert Sedgewick was a great teacher and I liked the way he explain lessons, for me every week assignment wasn't easy, but I enjoyed learning and understanding new things.

Thank you

Great course. I learned a lot. Biggest struggle was the setup and using Java. I had not really used Java before. So the instruction and material explaining Java could be better. That's the only reason for 4 stars and not 5. The videos on how the algorithms work conceptually is really well done.

Great course, covers many aspects of algorithms. The assignments with the autograder are great too. But the estimated time for an assignment is in my opinion far too low. In my case, to complete an assignment, I had to spent many more hours than the estimated 5 which the course indicates

Though a wonderfully structure algorithms course it suffers the most commonplace of problems i.e. sticking to a specific language for the whole course. If we don't consider that to be a problem it's really enjoyable with respect to both the coursework and the assignments as well.

This course is very helpful with me. It helps me review a lot of materials about algorithms I've learn from my university. Thanks professors and other members for a great course. If you want to solid your knowledge, don't hesitate to take this course, it's total worth it.

The course was really good in giving real time examples of the algorithms and its usability in the real world ,the course should also have offered few more assignment covering each topic in the assignments using every component of the course!

Excellent Course. Very Good Assignments and the Autograding feature.

Some of the topics are difficult to understand. So, I think their explanation should be as per level so that all the students can understand instead of moving forward.

I took this course to get a taste of Coursera courses and a refresher on my algorithm. The course is very informational and clear (Robert is a great professor) but the home assignments are much more challenging than the course material

Great course. Sedgewick has good educational skills. The course also contains good examples and interesting assignments. I struggled a bit with the first assignments, but then I liked the last 2 better. Looking forward to part 2.

Excellent course. Good lectures and interesting and challenging problems. Only drawback is that we are forced to use Java. It obviously helps with grading, but would have liked to use a language I am more familiar with.

The course focuses on Java specific implementations of algorithms, so if you're not from a Java background, you would have a little difficulty with the assignments.The course content however is great.

I think it is a good course. I have known more about time complexity of algorithms and some applications of different kinds of the algorithms. I have spent more time then I though for this course.

It is really good course. However for me, I took more time than the specified to solve the problems. I needed to do some research in the forums, because the instructions were not clear sometimes.
