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

The bad handwriting of the instructor is not a trivial issue as he pretends. He also talks very fast that makes it hard for people whose native language is not English to follow.

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.

This course requires mathematical backgrounds. The professor talks super fast and sometimes he makes you asleep..

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 explanation could be better. The hand writing must be improved.

Not practical enough, too academical approach for me.

Good course

He's a personable instructor, but I think there are too few examples, the course is too devoid of interesting history, and the language and assignments can be unnecessarily obtuse. I'll happily work through a challenging course, but it feels like a waste of time if most of your effort is spent translating.

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.

it can be better if the professor tried to learn more algorithm instead of focus deeply on them

Too theoretical, a bit too far apart from industry.

I had high hopes for this course, given a rating of 4.8 stars. I made the mistake of enrolling in the class without reading the reviews.

The instructor is, frankly, not excellent at explaining concepts. Even though I had already known most of the materials taught in week 1, I still had trouble understanding the instructor. I am quite disappointed. Having completed week 1, I figured unenrolling the course would be the best option for me.

Lesson learned: ACTUALLY read the reviews (particularly the ones with low ratings) before enrolling in any classes.

Note-taking was not possible.

The speaker speaks so fast.

The instructor does not explain simply, rather closer to being unnecessarily complicated.
