Chapter 12<\/h1>\n

Here’s were we will put color versions of the images, updates, and other extras.<\/p>\n

Here we will develop a different example of the same type of simulation as was developed in Chapter 8 and then look at several ways to modify it, such as adding customer priorities and preferences.<\/p>\n
