With the source code available and the user community growing, it seems
that there's a lot of potential for expanding the ADMB documentation in
areas like the one Hans described, where the current information is
brief. Arni noted the potential for user-generated contributions to the
source code, but it seems to me that the documentation is be even
easier to contribute to. I've certainly benefited from searching the
source code for information about how specific calculations are carried
out and I think a bunch of users sharing such information would be a
real benefit.<br>
<br>
This raises two questions for me. First, might there be a division in
the future between the
"Introduction to ADMB" document and a more technical
document? Second, how best might the community
take note of findings and understandings in a less formal way than
proposing specific changes to the official ADMB documentation? Are the
"community" pages at <a href="http://admb-project.org/">admb-project.org</a>
the place to go?<br>

<pre wrap="">Hi,
About this issue (for SEPARABLE FUNCTIONs) the manual says:
"Objects defined in the PARAMETER SECTION must be passed as arguments
to g_cluster. There is one exception: the objective function g is a
global object, and does not need to be an argument."
I do not know the details of how this works. Look at a few examples
to see how it is done.

<pre wrap="">Another strange thing is that if I try printing the value of the
objective_function_value g;
in a SEPARABLE_FUNCTION
it has the value zero there and is actually set to zero
but then returns what it is assigned in the function
so it is not like a local variable.
If the function is not separable this does not happen.
