Advice.
The slides are intended for the lecture presentations;
for reference, read the indicated sections from
Algorithms, 4th edition.
An effective strategy
is to skim the textbook before the lecture, then read it thoroughly
soon afterwards.
We recommend printing the slides before lecture and
annotating them during lecture.
Online viewing and printing. These lecture slides are suitable for online viewing (one per page) or printing (four per page).
Errata. Here is a list of known errors in the lecture slides and textbook.
