Document Ultranest interface BXASolver #11

Closed alexkolo closed 3 years ago

alexkolo commented 5 years ago

Since Ultranest is online now, will the next update of BXA also using it instead of Multinest? Under the hood both packages are doing the same, I assume (or are there some performance improvements as well?). However, with Ultranest the installation of BXA should be much easier, right?

PS: nice package naming ;)

Yes, it is in fact already available, through the bxa.xspec.solver and bxa.sherpa.solver API. You can prevent loading of the multinest library by setting the environment variable WITHOUT_MULTINEST to 1. There are still some minor differences to be understood, and you can help with testing.

Great. I'm not using it at the moment but a collaborator will start using it rather soon.
