Particle swarm solver not available in Global Optimization Toolbox

I know we should not use app for these as it is going to be removed in future, but I just wanted to try it once.

I have Global Optimization Toolbox installed but still around 5 solvers are missing in it.

Will reinstalling the toolbox work?

TIA

It is not possible to install R2020b toolbox on R2019b. Do you have the toolbox installed? You can check it by running

ver globaloptim

If it shows a warning, it means that the toolbox is not installed.

My bad! I guess it's 2019 only. I got this result on running this command

So why am I having problem? Can you tell please!!

Are you not able to use particleswarm function? What is the error? What is the output of

which particleswarm

[SURBHI GOEL]

Ths command is giving me the path correctly but when I go to the optimization app, I don't get particleswarm as solver in the dropdown menu (shown in the image attached)

Hi,

Optimtool did not support all of the solvers in Optimization and Global Optimization Toolboxes.

If you have installed or have access to R2020b, we've introduced a new UI that has the newer solvers including particleswarm.

Here's a video about it if you'd like to get a sneak peek.

I just checked and saw I don't have optimize option when I go to Task.. What should I do?

Thanks

[Steve Grikschat]

Do you have R2020b? That's when the Optimize task was released.

[SURBHI GOEL]

No. I have R2019B

If you read the description on the documentation page: https://www.mathworks.com/help/optim/ug/optimtool.html you can see that particleswarm is not available in the optimization app. You will need to write the code to use particle swarm.

Thank you
