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