[ADMB Users] a difference in estimates between versions?

[dave fournier]

It is always interesting to see what kind of posts produce the most 
response.
certainly none of mine. Anyway
there are a few standard things you can do to narrow this down.
First is to take the output from each model and put it into the other 
version and see if the numbers
stay the same. That verifies that the code produces the same function 
value. Also
you could reduce the convergence criterion as in -crit 1.e-6 to see if 
you can get a little closer to the
actual minimum.

Although it is not relevant to the discussion your approximation to the 
differential equation
for the population dynamics is gross.  See the semi-implicit version in 
the original
manual for an idea of how to do it right.
