About the Course

The primary topics in this part of the specialization are: asymptotic ("Big-oh") notation, sorting and searching, divide and conquer (master method, integer and matrix multiplication, closest pair), and randomized algorithms (QuickSort, contraction algorithm for min cuts)....

Well researched. Topics covered well, with walkthrough for exam.le cases for each new introduced algorithm. Great experience, learned a lot of important algorithms and algorithmic thinking practices.

Thank you for teaching me this course. I learned a lot of new things, including Divide-and-Conquer, MergeSort, QuickSort, and Randomization Algorithms, along with proof for their asymptotic runtime

I was glad to get exposure to famous algorithms through this class, but I don't feel like I really developed an intuition for reasoning about their runtime. The class was challenging, but mostly for the wrong reasons. I spent more time and energy pouring over the answers to tricky quizzes and having to implement algorithms exactly as described in the lecture notes rather than really truly learning. It also took me much longer than the 4-8 hours per week advertised to complete each week.

It would be nice to see more examples especially were we have too many formulas. I still confused with probability.

Also hadwritting isnt really helping. I am most of the time decoding scripts. In addition he is reading the formula at one moment and in around 3-4 seconds it appears on the screen. So I kind of listening him while trying to read what is happening on the screen. horrible experience.

This is not very beginner-friendly course, and what made it worse is that all the videos are out of sync (I don't know why this problem has not been addressed for 5 years), and the instructor's speaking manner is not easy to follow for a foreigner. Also a lot of the subtitles are just wrong. Otherwise a great course, if you keep on it you can learn a lot.

I do believe that feedbacks are very important during the learning section. Without feedbacks I would not understand whether I am doing ok or not. The Quiz and Homework would not handout the answer key and explanation after I have done. How am I suppose to be successful with the class if I don't understand which part I should strengthen.

This is a good course. I recommend everyone to take it. There are many details useful for you to learn. But it is not friendly. The words the professor used are not easy to follow for a non-native English, the way the exercises are designed is not reasonable. It could have been better.

The professor is very good. However, pictures and graphics mean a thousand words. These lectures rely too much on words. It makes it how to visualize the concepts. Hope to see more pictures. Animation will be the best.

Seems a bit dated, videos are reused from older courses and sometimes don't fit well together anymore. Content is great and lots of fun to work through.

Very hard but its manageable. Make sure to watch videos multiple times to understand the concept.

Great course theory wise, but the programming problem is unrelated and gives too little practice

Audio out of sync, sometimes material climbs in difficulty without the climb in explanation imo.

The content is good and the instructor is good. On the other hand the fact that you cannot submit assignments or problem sets without purchasing the course is quite annoying. On all other courses which I have done without purchasing, you were able to do the full course which includes the problem sets etc.

Es complejo llevar el ritmo del intructor, los subtitulos en español son muy malos con partes de "No audible" y usa mucho notas a mano lo que hace aún más complejo entenderle. Lamentablemente es un curso que no podré terminar :/ .

CODE ALSO NEEDS TO BE TAUGHT. ONLY ALGO WAS GIVEN

The content is good, but what is the point of having problem sets when you do not even show the solutions to it. How would a student work through if they get stuck at a question in the problem set. Some other courses from Stanford, such as the Introduction to Mathematical Thinking include solved answers to problem set questions in the lecture videos unlike this one. Highly disappointing.

انا افهم الكورس بالكاد بسبب اني درست تلك المعلومات من قبل لكن شرح الاستاذ معقد للغاية ولا يناسب اغلب الطلاب

I have done the homework. However, I need a supercomputer to do you calc. I'd like to exit.
