Optimization
I Mathematical Preliminaries:
Optimization of unconstrained functions
Consider the problem of determining the maximum and minimum values of a function f(x) of one
variable or a function f(x, y) of two variables or a function f(x1,x2,x3,xn) of

Assessing and Presenting Experimental Data
Common Types of Errors:
Error is defined as the difference between the measured quantity xm and the true
value xtrue :
Error = x m x true
When designing an experiment, our prime objective is to minimize
