Announcements (As of
December 20, 2013 10:27 PM)
- The second take-home has been graded. Exam scores and overall course
grades may be viewed on "Gradebook
2" in Sakai, and I have submitted course grades to the
registrar. The solution
may be viewed on Sakai. I hope everybody had an illuminating
semester, and best wishes for the holidays.

Handouts, Class Materials, and Assignments
- Thursday, September 5: Introduction, basic convexity concepts -- convex sets,
epigraphs, convex functions, closed/lower semicontinuous functions,
differentiable convex functions, convex and affine hulls
- Thursday, September 12: A bit more on differentiable convex
functions, combinations and hulls, cones, Caratheodory's theorem, relative
interiors
- Thursday, September 19: Finish relative interiors, basics of
optimization, start projection
- Homework 2, due September 26 (disregard problem
3, which will be moved to a later homework)
- Please read Section 1.5 of the text, regarding recession cones.
Most of the proofs are not critical, except Proposition 1.5.1 (a)-(c)
and especially (b). I did not have time to cover this material in
class.
- Thursday, September 26: Finish projection, separation
- Thursday, October 3: Polar and dual cones, polyhedral cones and sets
- Thursday, October 10: Subgradients and subdifferential calculus
- Thursday, October 17: Proof of (simplified) Rockafeller-Moreau
theorem, deriving optimality conditions and constraint qualifications from
the Rockafeller-Moreau theorem (also, start conjugate functions if time
permits)
- Thursday, October 24: Conjugate functions
- Thursday,
October 31: Fenchel and parametric duality for optimization problems
- Thursday, November 7: More parametric duality
- Thursday, November 14: More parametric duality, monotone operators
- Thursday, November 21: Monotone operators, nonexpansiveness, finding
fixed points of nonexpansive maps
- Tuesday, November 26: The proximal point algorithm, augmented
Lagrangian algorithms
- Thursday, December 5: More augmented Lagrangian algorithms, the
alternating direction method of multipliers (ADMM)
