[janosg]

Hi @gauravmanmode, yes this is still relevant!

[apoorvalal]

thanks for taking this on, @gauravmanmode ; happy to answer any questions. The examples in the pyensmallen repo should give you a good start.

can i work on this at the same time? @janosg @apoorvalal

[janosg]

Hi @AashifAmeer, let's not duplicate work (unless you know each other and are working together). I opened #560 as alternative issue you could work on.

[AashifAmeer]

@janosg ,sure, will work on the next issue

[gauravmanmode]

okay i will see the examples and try to understand.

To add an optimizer:

⬜️| Translate the names of all frequently occurring tuning parameters to our naming scheme and find good and descriptive names for the remaining ones
⬜️| Translate the optimizer output to an optimagic.InternalOptimizeResult
⬜️| Provide information about the optimizer via the mark.minimizer decorator.
⬜️| Create a subclass of Algorithm and do the actual optimization in _solve_internal_problem
⬜️| Create benchmarks and improve the default values of tuning parameters.
⬜️| Write documentation
