hi. does anyone know if there is a good/free/popular c++ library for
nonlinear conjugate gradient minimization?
i.e. somthing that takes a f(x)=y and minimize for x.
i also need it to be able to use automatically computed finite
difference derivites rather than user supplied ones. thanks!

Have you tried www.google.com? It's a secret web site nobody knows
about and it might help you... Just don't tell anybody I told you.
i tried that first, but i wasnt able to find anything.

Really? Wow.. Means the web site wasn't that secret after all...
So, you're saying you didn't find OptSolve++ or GSL or... ? Hmm... http://tinyurl.com/aj9jd

optsolve++ doesnt seem to be free, and gsl doesn't seem to include a
multidimensiona l minimizer that doesnt require user computed
derivatives. it appears that you have to specify it in the
gsl_multimin_fu nction_fdf object.
unless i am missing somthing

Probably that free cheese exists only in a mousetrap.

Try Numerical Recipes. It's not free, but worth having it. The book is
also online, free, and contains the code. Just cut-n paste. Convert to C++
if you want. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi!
Does anyone of you know a python library to find minima of
multivariable mathematical functions?
I know that in SciPy there is what I need, however I wonder if there is
something lighter without the need to install the whole package.
Thank you a lot,
Stefano

All,
This is a general question regarding how, and if, compiler optimization
techniques affect the general concept of being able to update a component of
an application without requiring a recompile of client code.
For example, suppose I have component: common.dll which defines several
constant values, say Const_A, Const_B and Const_C. Further say I have some
client code in another component: client.dll which references common.dll and...

Hello all,
I have written an expression interpreter, and a profiler has told me that a
specific part of it is in need of optimization. My purpose in posting to
this newsgroup is to solicit suggestions on how I might accomplish my
intended aim more efficiently.
My interpreter supports the "if-then-else" construct. In addition, it
supports variables, which means it has a symbol table. As you probably
suspect, the symbol table is...

Hi, I have written code that I would like to optimize. I need to push it to
the limit interms of speed as the accuracy of results are proportional to
runtime.
First off, would anyone know any resources that explains how to optimize
code i.e. give some rules on c++ optimization? e.g. using memcpy to copy an
array (which i have done).
Also, what is the best sorting algorithm out there for sorting an array of
of size 100 or less? I have...

use string.Compare rather than myString == myOtherString,
etc., etc.
I have been searching for days now for that article or those performance

Computational
Time is of high priority. One approach can be to use ready functions

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
