CS 730: Nonlinear Optimization II  Spring 2016

Schedule
In general, classes will be held on MWF every week, and lectures will be 60 minutes, but may take up the full 75minutes slot on several occasions. I will be absent on a number of MWF days, and the longer lectures will make up for these absences. Class time will average 150 minutes/week.


Office:

Office Hours: 
(tentatively) Monday 34, Thursday 34 


General Course Information
Prerequisite
 CS / ISyE 726 or equivalent. (See me if you think you have done an equivalent course.)
Text
 J. Nocedal and S. J. Wright, Numerical Optimization, Second Edition, Springer, 2006. (It's essential to get the second edition! The version published in China in 2006 is a reprint of the first edition, so is not suitable.) Here is the current list of typos.

Lecture Notes
These can be found here are updated sporadically. They are mostly for my own benefit and hence are terse, and refer heavily to the text in places. I supply them to help you fill in any missing details in the notes that you take in class.


Course Outline
 Geometric viewpoint of constrained optimization
 Convex sets, cones, projections
 Tangent and normal to polyhedral sets
 Theorems of the alternative, separation results
 Firstorder conditions: polyhedral case
 Stochastic Gradient
 Optimality conditions for nonlinear programming
 Constraint qualifications
 Firstorder conditions and saddle points
 Secondorder conditions and critical cones
 Degeneracy
 Duality for nonlinear programming, including Wolfe and Fenchel duality
 Nonlinear programming algorithms
 Fundamentals: merit functions and filters, Maratos effect.
 Interiorpoint and augmented Lagrangian methods
 Sequential quadratic programming
 Secondorder cone programming and semidefinite programming: applications, barrier methods.


Assessment
(The scheme below is provisional and subject to change until the third week of semester.)
First, some rules. I'm serious about these!
Violations will be penalized energetically.
 Submitting someone else's work as your own is academic misconduct. Such cheating and plagiarism will be dealt with in accordance with University procedures (see the Academic Misconduct page).
 You may discuss homework with classmates. However, you may not share any code, carry out the assignment together, or copy solutions from another person. Discussion should be verbal only. The submitted version must be worked out, written, and submitted by you alone.
 You may not discuss takehome exams with anyone while
they are in progress, except the Instructor.
Keep track of your grades through the learn@uw system.
 Approximately 8 homework
assignments, 35% of grade. Some of these will
be graded by class members, using a key
supplied by me.
 Homework is due at the beginning of class on the designated date.
 No homework or project is accepted in mailbox of instructor.
 MIDTERM, approx 25% of grade. (Probably a takehome.)
 FINAL, approx 40% of grade. We
will probably have a takehome exam that is due at the end of the
scheduled exam time, and possibly will be submitted online. The
nominal date/time for the final is Friday 13 May 2016, 2:45pm4:45pm.
