            <div>
              <p class="MsoNormal">I've recently installed admb 10.1 on
                a 'real' system (SuSE Linux Enterprise<br>
                Server 11 SP1, gcc 4.3) and I've noticed different
                behaviour vs my 32-bit<br>
                admb 10.0 windoze setup. Specifically the ic > imax
                is minimum attained<br>
                issue pops up on the 10.1 where it does not on the 10.0.
                Both installations<br>
                give me the same parameter estimates, but obviously a)
                something is<br>
                different, b) it appears to be worse in the newer
                version and c) it would be<br>
                nice to know why. The first thing that came to mind is
                that the default<br>
                value of the convergence criterion might have changed
                between 10.0 and 10.1<br>
                but I ran the new system with -crit 1e-4 and same
                behaviour.<br>
