Hi Art,
I presume you're using Version 6? It sounds like you know what you're
doing, but perhaps haven't come across the various options for
FindMinimum? Paste the following into the Help>Documentation Center
address field:
tutorial/UnconstrainedOptimizationOverview
which should bring up a jump-table of links, including the one
pertaining to FindMinimum:
"Methods for Local Minimization"
Perhaps tweaking the L-BFGS "step memory" or switchng to the the
ConjugateGradient method?
Good luck!
