I just compiled revision 172 and discovered that my complaint from
yesterday has been answered. The -version command now works and
produced this useful info:<br>
<blockquote><tt>ADMB-10.1 safe libraries compiled with Gnu C++
4.5.2(64bit)<br>
Build date: Oct 6 2011<br>
Revision: exported<br>
<br>

and ADMB Foundation</tt><br>
</blockquote>
For the record, the estimates from the model we've been discussing
were not different from those I sent yesterday.<br>

First, let me note that if it hasn't been fixed already, it would
be very valuable to reintroduce the option to output your ADMB
version number at the command line. And maybe we could have more
digits in the version number or also add output of the source code
revision number.<br>
<br>
Using 64-bit linux with ADMB 10.1 (installed through the IDE and I
think without bug fixes added in), I get the following:<br>
<blockquote><tt>$ ./gbytffall -maxfn 5000<br>

and the quite different parameter estimates (no std file):<br>

When I get a chance, I can try to compile the bug-fixed version.<br>

There was no difference in values amongst the versions. You will note
though that these values are slightly different from the ones he
supplied for ADMB IDE 450-1. This suggests to me that it is either a
32-bit-64-bit difference or a windows difference.
Can anyone else run the attached model for 64-bit on linux and windows
or 32-bit on windows for the two versions of ADMB and report the .std
file for comparison?

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.
