Dear Users,
I have a program in which I am trying to minimize a
function several times in a program.To me finding the local minimum is
sufficient given a good intial guess and constraints.However , Mathematica's
built-in FindMinimum seems a little slow since I need to make repeated use
of it(I tried the global minimization but it is much slower ) several times
with different intial guesses and constraints .This depends upon the
function too ofcourse and the time taken could be improved by changing the
accuracy /precision. Is there a way I can get my program speeded up in
anyway possible( Try changing the value of 'nn' in my program I upload and
observe as 'nn' gets bigger so does the computation time needed ).I am
uploading my notebook at
http://uploading.com/files/mb1cd236/sampleprogrammath.nb/
Thanks in advance !
Nabeel
