Hello everyone,
The optimization subVI's with labview (most of them) solves for local minima. Is there any subVI which does the global minimization and gives estimates?

From Wikipedia:
"Finding an arbitrary local optimum is relatively straightforward by using local optimisation methods.
Finding the global maximum or minimum of a function is much more challenging and has been practically
impossible for many problems so far."

If you have a specific method that you know of and would like to use, you could likely code that in LabVIEW.
What method were you considering using for estimation?

Thanks Tori for discussing.
I have used the available subVI's for finding parameter estimates and it has worked well so far.
But someone pointed out that there is a chance I am being trapped by a local minima and to see if I can work a solution around it.
I am thinking if anybody has tried to this coding in LabVIEW, specially coding the simulated annealing method.
The thing is I have found I can do all analysis and everything I need to do with LabVIEW so I dont want to deviate to any other platform.
Plus have been using labview for the past 11 years :), so trying to see how best I can do this.

So I am not able to find any these type of methods coded already. I think it would be great to add this
to our Idea Exchange board to generate some interest in it. This would also make a great community example
if you are able to generate some sample code. Sounds like an interesting idea overall and I wish you luck.
Keep in touch if you have any more specific questions about implementing this.
Best,
