Caltech CS 150 Probability and Algorithms, Fall 2018 Leonard J. Schulman
My office hours are by appointment at the beginning of the term, after that
I'll fix a regular time (but appointments will still be fine). Starting Oct 12: my OH on Fridays at 11:00.
TA: Jenish Mehta, firstname.lastname@example.org.
Added December 17: Revised and collected lecture notes for the whole term.
