My students: materials here are meant to supplement lectures.
If you find any inaccuracies, please let me know and I'll correct
them either here or in class.
For people who are not registered in these classes: use these materials
as you wish, but I do not guarantee their accuracy (especially for
portions that I don't have time to include in the course!).
A good example is my very old
non-linear programming introduction, for which
I've received numerous requests;
it seems to have inaccurate bibliographical remarks, and
perhaps other errors; use at your own risk!
