Hi Derek,<div>Sorry for my previous runs which has big gradient and hit the max function evaluation and being ignored by me.</div><div><br></div><div>I rerun the ADMB catage example, which agreed on the same results on windows 32 bits ADMB 9.0 and latest source built ADMB 10.1, also on ubuntu 64 bits latest built. So the problem is coming from his model, there is nothing related with ADMB.</div>

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