Dear All,<br><br>I am a new user of AMPL and IPOPT. When my objective function contains <br><br> round(x,n), <br><br>ipopt crashes with:<br><br> exit code 3221225477<br><br>Does this mean Ipopt can not handle this in objective function? Is there an alternative way of getting the same result?<br>
<br>Sincerely Yours,<br><br><br>Novalio Daratha<br><br><br>
