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.
