This document discusses optimization techniques in chapter 8. Section 8.1 describes optimizing a flexible gripper by adjusting the Y-coordinates of certain points to reduce stress while staying within defined ranges. Section 8.2 describes optimizing a triangular plate by adjusting the width and radius of a fillet to reduce material usage within given ranges. Key concepts discussed include input/output parameters, design points, goal driven optimization, design of experiments, and optimization algorithms.
