Average-case complexity and statistical inference.

Notes from each lecture will be uploaded after the lecture. The course information is here and includes dates. Generally we meet Wednesday 3.15-5pm in the seminar room in house 6 : Spring 2023.

I'll maintain cumulative lecture notes (last updated 24th May). Link to the first exercise sheet is here, and second exercise sheet is here.
