I've obtained a licence for non-comercial, academic use of the SQP optimizing routine FFSQP from Zhou, Tits and Lawrence, Univ. of Maryland (http://www.isr.umd.edu/Labs/CACSE/FSQP/fsqp.html). I plan to use this with python, with help from Pyforth. Has anyone made the necessary modifications to the main sub-routine and written the .pyf file? Olaf -- * Olaf Trygve Berglihn <olafb@pvv.org>
