Checkpointing in nlopt

[yugeniom]

Hello,
I am using nlopt in conjunction with meep adjoint. I would like to set checkpoints in the optimizations I make. Does nlopt natively allow for something like this?

Thanks

No not currently. (It would require us to go through all of the algorithms and figure out what state needs to be saved.)

Of course, you can always save the current best solution and restart a local optimizer from there, but that is not exactly equivalent to checkpointing.

Hey guys,

Has there been any update on this aspect?
It would be nice to have the optimizer-state exposed so that we can continue optimization!
