He's been giving himself ratings on here because no sane student could rate this positively, if negative ratings were possible, they'd be reserved for people like this. Very inhumane. Save yourself the trouble

Prof. Lokshtanov is a super engaging lecturer. His exams/homework are hard because the material is hard. He genuinely wants us to learn, so he avoids questions that test for memorization, which results in very complicated premises--most of the time I struggled with understanding the question. He's also caring and accessible through office hours.

I don't know why he's not rated higher. Incredibly good lecturer, really makes sure you actually understand the material. Homework was fair and tests were generously curved (and they weren't crazy hard or anything.) He made difficult concepts, like dynamic programming, seem simple.

Hardest class I've taken. He had no idea how hard to make the tests, since he's very smart and struggles to think down at our level. I did enjoy lectures, he was passionate and left me at a loss for words every time (I was lost). The few people who understood everything made sure to let everyone know they understood everything. Generous curve.

He's a passionate lecturer that's for sure. But that's really as far of credit as I can give him. Most times I felt I was learning significantly better from just youtube videos. Not the best at making his lectures easy to regurgitate. Doesn't provide much if any resources besides "go read the textbook". Doesn't post any notes. Best to avoid.

Lectures are super thorough and you can tell he really loves teaching algorithms. You have to make sure you're ready to understand and paying 100% attention during lectures though because if you get distracted even for a few minutes, you will be completely lost. Exams are really hard but very good prep for CS internships and interviews.

Prof is super knowledgable about subject, but bad at explaining concepts to those seeing them for the first time. Lecture material not provided outside of class, and exam questions are confusing.

Professor Lokshtanov is disconnected from the course material and doesn't understand its difficulty. While he is a passionate lecturer, he gives exams harder than his lecture materials where the averages are low Ds and Fs. He isn't good at breaking concepts down and teaching at our level. I loved the material just not how he teaches it.

Algorithms classes are hard. However, they are essential for coding interviews, so quality of instruction is really important imo. I also took 130A with Lokshtanov. You can tell from how he teaches that he is both incredibly knowledgable and also invested in helping you understand the material.

Great lectures, he has a deep understanding of the material. But you REALLY need to practice algorithms, he won't be lenient on the exams. I see a lot of people blaming him for the low avg on midterms, but this is probably the most important class in CS, and it's good that he's preparing us for interviews. Algs are not supposed to be easy.

Very difficult HWs, Exams were not too easy either but were graded generously. Be ready for lots of work

Took during covid. there are no exams, only hw and programming assignments. hw is a bit hard but programming assignments are easy and can give you extra credit. He drops lowest assignment. I never went to lecture or section, got a B. his lectures are decent.
