Hi All!<br><br> I have reardt in the Ipopt List this comment:<br><br> "In Ipopt there is already (I think) a code to evaluate Hessian by finite differences. It can also be used in Bonmin"<br><br> I would like to know if really exist the possibility of aproximmate automatically the Hessian in Bonmin in a similar way as it could be done in Ipopt (limited_memory option), because I can´t find the option in Bonmin to approximate the Hessian for solving MINLP problems.<br><br>Thanks a lot<br><br>Regards,<br><br><br>===========================================<br>Alberto Jorrín Rodríguez<br>Departamento de Ingenieria de Sistemas y Automatica<br>Dpt. of Systems Engineering and Automatic Control<br>Universidad de Valladolid / University of Valladolid<br>Address: Facultad de Ciencias, c/ Real de Burgos s/n<br>47011 Valladolid, Spain<br>Tel: +34 647 670 581, Fax: +34 983 423161<br>e-mail: albejor@autom.uva.es<br>============================================<br><br><a href="http://www.microsoft.com/windows/windowslive/default.aspx"><br></a><br /><hr />Disfruta antes que nadie del nuevo <a href='http://download.live.com' target='_new'>Windows Live Messenger</a></body>
