This directory contains lecture notes for CSC2/458. As of January 2019, the notes are from the last time I taught the course, in spring 2017. I'll be updating them as the semester progresses. Check the line at the top of each file to know how new/old it is. Please note that these notes are posted on an as-is basis: no guarantees are made wrt to correctness, or to how well they will correspond to what's covered in class.
