I thought I would start by maybe the most uh outstanding example uh in this direction of linear programming so linear programming it's an whole area it's linear algebra with inequalities that's what it really is about and um the whole area just sprang into existence after World War II or in the in the developments of World War II uh I guess the name the most famous name in linear programming is uh daning who created this uh Simplex method pretty unusual for a method to um survive fundamentally unchanged for such a long time that the that the first method suggested to solve linear programs should turn out to have such a a long life and still still very alive uh with competition now from uh a different uh a different class of methods but the I hope you'll feel that this subject is kind of fun uh I'm picking linear programming well I'm just creating an example here uh to show what Duality is about um and then the second lecture this afternoon please s...

PROFESSOR: All right, I thought he would be. It's always a hazard putting up somebody who you know is going to lecture better than you do. But I hope that was a good change of pace. And, of course, he knows more about the subject of Reed-Solomon decoding than I or more than practically anyone else does, so -- did he have much time to talk about decoding or was the most -- yeah. Talked about the decoding algorithms, Sudan-type decoding algorithms. Yeah? OK. Good. Well, in fact, he covered so much that I don't have much left to do today. I remind you, Ashish put out an email. There's a review session tomorrow for the midterm from 5 to 7 in a different room, 36-112. The midterm is Wednesday in this room. It starts at 9:05 to give you a little bit more time to work on it. It's closed book except that you're allowed to make up three normal size sheets of notes. You can write as small as you like. This experience has shown this is the very best way of gettin...
