Default subsidiary algorithm in NLopt AUGLAG

Specific Domains Optimization (Mathematical)
1

I wan to use the NLopt’s Augmented Lagrangian algorithm in JuMP environment. In the documentation it is mentioned that the AUGLAG algorithm uses a subsidary algorithm for the optimization and that this local search algorithm can be changed by user. However I could not find any information about what the default subsidary algorithm might be. Is there possibly a way to check in JuMP environment which algorithm AUGLAG is currently using?

Thanks beforehand.

There isn’t one. It defaults to NULL and AUGLAG will throw an error if you didn’t specify one. Documentation PRs are welcome.

Thanks for the answer @stevengj. I want to specify that I’m using :LD_AUGLAG and I’m not getting an error. The optimization works as it should. I still wonder which subsidiary algorithm this one is using.
