15.094  Systems Optimization:Models & Computation

Hello all -
this week's lectures of 15.094 will focus on case studies of use of optimization in various applications. The topics and presenters are:

• Tuesday, 5/15: Brian Anthony, MIT, "Optimization in video processing and analysis"
• Thursday, 5/17: Mustafa Sir, University of Michigan: "Off-line adaptive radiation therapy"

See you there!

I am forwarding along a tip from one of the students that some of you might find useful:

"Dr. Epelman,
 
Concerning these last two problems, I'm not sure if anyone else has had the problem of the mex files not compiling, but on some of the athena lab machines before you can run Installmex, you have to change the C compiler settings in matlab by typing "mex -setup" and then choose option 2. If anyone has a problem with their compiler not support C99 stuff, you might want to tell them this.

Just to remind you - the answer to part a) of problem 1 was actually discussed in lecture 20 (slide 37). You can use these answers to verify your approach is working, before starting the other parts of the problem.

Hi everyone,

In part a of Homework 6, Exercise 1, you have to assume average values for the gas turbine operation cost, the coal operation cost and the growth as well. Do not assume any probability distribution for the growth.

Hi everyone,

Just a clarification for exercise 1 part b:
You compute the optimal allocation for every possible scenario #2-#5. Then, for every scenario #2-#5, you do the following:
- For every possible event of the probability model which is associated with some optimal allocation, you find the expected cost according to model #1, if this model is used.
- You take the weighted average of these expected costs, according to the probabilities of the model.
