Hey do you guys know of any tool that can help me optimize a rather complicated function?

Here is the exact function...

...and I need to find its global MINIMA (the max is part of the function) subject to:

Hi;

Mathematica can do it but I do not understand what you are asking so I am unable to use it.

You can try mathematica.stackexchange.com/

Oops sorry, I just need to find

such that the function is minimized. Also, I forgot to add in the constrains. Here are the constrains for copy-pasting:Offline

Here is the exact function..

I hope this makes the problem more readable.

I think you might be confusing things even more. The max function is part of the function. Should I say:

and I need to minimize S?

Hi;

Do you know what the answer is? I was unable to find a nice closed form but I have a good numerical value and a bound if needed.

Oops no I have no idea about the answer (that's why I posted the question in the first place) Numerical values would be nice...

I expected it to be around 25...

Thanks for the number to 20 places, but I really would have needed just 4 places. What about the

s? Actually, they might be more valuable for me...Offline

B0 = 0.1648056655557596774507804494

B1 = 0.14069040189635455254455518183

B2 = 0

B3 = 0.051135149049937002977770545

B4 = 0.3765373416468427935424526

B5 = 0.2668314418511059734844411905

B6 = 0

Thanks for the numbers. No

? This could potentially mean oversimplification of the original problem... (which is err my problem)Offline

You could force a B2 by changing the constraint to B2 > 0.

Nope that's not it. Either I have mismodeled my problem, or the optimal solution wasn't as I had expected.

What was the original problem?
