Fourth Example: Modeling (1.4) and

Practical Optimization (3.5)

An agent wants to maximize (or minimize) a certain variable, which we call the target variable. He or she does this by choosing the value for some so-called choice variable. There may be more variables involved, we call these the other variables. Consider the following example:

A piece of papers with dimensions 200*400 (pixels) as above is to be folded. We take the upper right corner and put it somewhere on the base line. Try this by clicking a little above the base line and the paper will fold.

Our aim is to minimize the length of the (blue) fold.

Look for next example
