How to minimize C++ function using boost?

Question

so I have a function like

int f(int i, int j, int c, double d) {
    /*...any operations with i, j, c, d affect on some return int we have*/
}

Is there any thing in boost or STD that would take my function and find the input arguments that minimize my function output?

Answer 1

I understand you to be looking for code to perform mathematical optimization.

Boost does not have anything to do this as far as I know, and neither does the standard library; however, NLopt may be what you're looking for.

Answer 2

I assume you're trying to do a "simple" mathematical multi-dimensional minimization.

GSL has some functions to help you with this. I wouldn't look any further ;)

Answer 3

You can use Brent's algorithm to minimise simple functions.
