Professor Cho had to teach a very difficult class in a tough situation this quarter and I think he honestly did better than almost every other CS180 teacher besides maybe one or two of them. The concepts of the class are very difficult in general but I think he did a good job of trying to teach each concept while providing further resources in the textbook. He gave us reasonable time to do each homework and complete both the midterm and finals. Even though the final was a lot harder I think that was in part due to the concepts on the final since it wasn't cumulative. I don't think the people complaining about him this quarter have ever taken the class with one of the other professors who are much worse. He is a super nice guy and always takes time to answer questions in class and overall I enjoyed my experience much more this quarter than with other professors.

Professor Hseih is very nice and accommodating for students (during the COVID-19). He offered 24-hour midterm and 72-hour final. There were total of four homework assignments due which took some time, but most of it was Googleable. He often gave out extensions for the homework deadlines.
The midterm was pretty easy (median of 96~98 I believe) but the final was very tough. It actually took at least two days to complete and the median ended up being around 83. Both exams were open note.
Although Professor Hseih teaches by the book, he does not have a neat handwriting, so it's often pretty difficult to decipher his handwriting. I think he would've taught a lot better if he was in person. For more difficult topics like DP, NP, and DAC, I usually resorted the textbook (which was also kind of confusing) and a lot of YouTube videos.

For the online version:
Lectures were pretty messy since he was constrained to an ipad, he would probably be better in a lecture hall with a lot of whiteboards. I ended up not going to lectures after week 5 because I couldn't follow. So a good part was he gave us 24 hours for the midterm and 72 for the final. The final was hard just because I think the concepts were a lot more difficult to grasp compared to what was on the midterm, but its not like the questions were unreasonably difficult, if that makes sense. I did end up using the entire time to figure out solutions for all the questions though, so that was really stressful three days.
The homework is not crazy hard and collaboration is fine.

Basically I would recommend this class if you are able to learn on your own, since he doesn't try to be unfair and trick you or anything. And if it goes back to in person his lectures would probably be much better than my experience.

Professor Hsieh was incoherent and a very poor lecturer. I eventually stopped showing up to class and only read the textbook since I never learned anything from him. He gave decently difficult homework but there weren't usually that many questions. The midterm was not too bad but his final was definitely very tough.

Professor is very clear and has this down to a science at this point. The textbook is INSANELY HELPFUL, even more so than lectures IMO.

This class involves some healthy mind-gymnastics to do well in. I ended up spending ~10h just solving each homework, plus an additional 5h writing up my solutions. Needless to say it was a little grindy at times, but this class was really good at getting me to understand the Algs. I wish we spent more time on Dynamic Programming, of which we basically only scratched the surface in this class.

He said we would have 500 homework points, worth 50% of our grade total, but we ended up having 350 points (4 assignments), so they ended up counting for a lot more of our grade. The midterm was fair, but took a looong time to writeup (24h window). The final had a 48h window, and even with all that time I still ended up not fully solving one problem. Pretty hard stuff for sure.

what all the other reviews said - homework takes a long time, but you get faster as you get more used to the patterns you need and become adjusted to the idea of trying many different solutions as opposed to kind of knowing which direction you're supposed to go in right off the bat. It's like a puzzle. Cho is great at explaining, but things can get a little bit muddy at some points - just make sure you ask questions if this is the case, because he is always, ALWAYS kind and willing to answer. Super accommodating, super kind. 100% would take this with him again.

He's okay. Lectures aren't terrible, but not particularly engaging or interesting. That being said, Professor Hsieh is a pretty kind person, and he is always happy to answer questions. The homeworks definitely take a while, so start early! If possible, try to find a friend to review the homeworks with after you finish; doing this really helped me solidify the concepts. The exams on the other hand... sucked. I know people that spent 14+ hours on the midterm (which had a 24-hour window), and the final took even longer. But all this means that the TAs need to spend more time grading the exams, so the grading ended up being pretty wack, where they'd be super lenient in some places and mark off points for no reason in others. Once testing returns to normal though, I don't foresee this being an issue.

Great professor. Not super engaging but explains concepts well enough to understand and use. Tests were time-consuming and hard but it is cs180. Overall, worth taking compared to other professors

Professor Hsieh did a great job teaching this class in the online format. For lecture, he wrote notes on his iPad with a stylus, and did a good job. He went through topics with thoroughness and clarity, and was more than willing to answer lots of questions.
The format of the class was very straightforward. There were four homework assignments, as well as a 24 hour midterm and 24 hour final. Most homework assignments consisted of four to five algorithms questions, and didn't take too long. The final and midterm were very similar, with varying degrees of difficulty between questions.
Overall, I would definitely recommend taking CS 180 with Hsieh. The workload wasn't too bad and I learned a lot.
