# Network Optimization

## Lecture Notes

Lecture notes are available for this class in two formats. We recommend you view the Microsoft® PowerPoint® (PPT) versions, if possible, because they include motion. The animations referred to in the lecture notes in yellow boxes can be found in the animations section of the course. Please note that slides for Ses #18 are unavailable.
