1. (20)
If you find that AskJef is not giving as good an answer as you want,
what two major changes could you make to improve the quality of the response.

2. (20)
GUS has two major systems allowing it to not repeat questions.
What are they?  Briefly explain how they reduce questions to the user.
(Hint, part has to do with GUS and part with FRL)

3. (20)
You are to find the best two values of x (x1 and x2) that
will cause the function f(x1,x2) to be minimum.
Only worry about values in the range -20 to +20.
Specify the details of the chromosome and as much of
the detail as you can the eval algorithm.
The eval routine does not have to be a valid program, but all
of the steps are to spelled out in code or English.

4. (20)
Specify a problem (not XOR) that would be a good problem to use a 
NN on.  
Be sure to specify enough to support your case.

5. (20)
Give problem that would be a good candidate for case based reasoning.
(Not AskJef).

Discus why there could be problems in building a corresponding 
rule based expert system.
Be specific (not just it is hard to do something).
