Lectures

Links to lecture slides and files will be available after class on the date shown. In the readings, KT refers to the Kleinberg-Tardos textbook, whereas E refers to Erickson. When readings from both are suggested there will generally be some overlap between the two textbooks; students are not expected to read both.
