<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><P>Hi,</P>
<P>Sorry to bother you. When I reset keywords mehrotra_algorithm and corrector_type,</P>
<P>the error message "Unknown Keyword" displayed. Does it mean current version of IPOPT </P>
<P>can not execute Mehrotra's predictor-corrector algorithm? If not,how to configure the </P>
<P>keywords to bring Mehrotra's predictor-corrector algorithm into effect? And the second </P>
<P>question is the total time spent by IPOPT is only "Total CPU secs in IPOPT (w/o function </P>
<P>evaluations)" or "Total CPU secs in IPOPT (w/o function evaluations)" adds "Total CPU secs </P>
<P>in NLP function evaluations" ?<BR> </P>
<P>Thank you in advance,and hope for your reply sincerely.<BR> <BR> <BR>Best Wishes,<BR>From Wei.<BR></P>
