Let me remind you of an important point that appeared in the assignment 
1 write-up and also appears in the assignment 2 write-up. It will be our
policy for the remainder of the semester as well. 

---
This is an individual assignment. Please work on your own. You are free to 
discuss the problem and coding issues with your colleagues, but in the end 
the program you submit should reflect your own understanding of Mutual 
Information and Perl programming. 
---

I have observed a number of programs where it is fairly obvious
that code has been copied. It is highly improbable that people
working independently (even if they are engaging in discussions of
the assignment itself and coding issues therein) will write large
sections of what is essentially duplicated code. It is particularly
obvious when this code is flawed in some way. 

So let me be quite clear. You are free to talk about the assignment,
you are free to talk about Perl. You are free to talk about specific
problems you are having in Perl in regards to an assignment. However,
you are not free to write code for another student, nor are you free  
to submit any code you did not write yourself. 

In summary, my expectation is that when you submit a program to me, you  
will have written that code yourself and that you will have done so in a  
largely independent fashion.

My apologies to the majority of you who have already met this  
expectation. I admire the creativity shown by many of you in pursuit of 
this assignment, and the diversity of your design and coding styles
clearly distinguishes you from those who may not have taken this
more difficult path.
