I'm working with a copy of Dr. Grefenstette's GA optimization program
GENESIS (v. 5.0), and I've come to a small problem.  Basically, the 
final solution isn't converging after 30000 total trials.  I'd like to 
extend the range of total trials so that I can go beyond 32767.

Since I am _extremely_ inexperienced wrt programming in C, I was
wondering if someone had already run into this problem and designed
a work-around for it.  My guess is that the global variables
"Trials" and "Totaltrials" need to be changed from "int" to "long."
However, I'm not sure what effect that will have on the other "int"
variables within the program.

I'm sure this is a trivial question, but as I mentioned earlier, I
have not had a great deal of experience with C.

If someone has any suggestions as to how I can fix this problem, or
can point me to a previously-modified version of GENESIS, I would
be very grateful.

Thanks very much for your help.
