[Based on the COM paper]

1. What portion of COM is modeled and analyzed in this paper?

2. State 3 interesting properties that Alloy helped identify about the
   COM model.  A property is more interesting if it would be difficult
   to detect with other kinds of tools.

3. Based on your experience with SMV, what portions of the COM
   modeling and analysis could you have done or not done with SMV?

[Based on the "Automating ..." paper]

4. Why does Alloy need to bound the number of atoms?

5. What part of Figure 1 relies on a bound on the number of atoms?

6. The paper talks about the difference between checking for
   consistency and validity.  What is this difference between these
   two kinds of checks from a designer's perspective (ie, what does
   each type of check tell you)?

7. What does skolemization do?

8. The paper uses trees to manipulate mappings.  The figures in
   section 3.3 resemble BDDs.  How are the trees as used here similar
   to and different from BDDs (think in terms of what operations get
   performed on them, how they are used, other characteristics, etc).
