Monday November 19

Finish the flocking model with the features we worked on in class. If you
don't have any more questions about it, email it to me. Also, if you haven't
already done so, please send me copies of the three previous models we've worked
on: the final version of the butterfly model, the simple birthrate model, and
the flocking model in Exercise 4. on p. 114.

We will start Chapter 13 on Monday by discussing Sections 13.1 - 13.3, so you
should read it over before class. You will notice that this time we do not have
a working model to look at; we will have to build it ourselves.
