There's the following algorithms class CS 261 (upper-level undergraduate/masters) and CS 361b (mostly aimed at phd students, though undergraduates take it). 161 covers all the material you would expect to see in an undergrad algorithms class. I'd be surprised if 261 or 361b are put online, since they're not usually recorded and (at least when I took them) have between 10 and 20 students.
