UltraNest support

Open JohannesBuchner opened this issue 3 years ago • 1 comments

Would you be interested to add support for https://johannesbuchner.github.io/UltraNest/ ? The interface should be very similar to dynesty.

UltraNest is a very reliable tuning-parameter-free algorithm. I have published some examples where the UltraNest algorithm is unbiased while multinest's algorithm (implemented in pymultinest,nestle,dynesty) gives a different answer. UltraNest is a pure-python package and very easy to install with pip or conda.

UltraNest also supports resuming from disk and MPI parallelisation, if that is useful to you. It can be faster than dynesty, especially if you take advantage of vectorization.

Hi Johannes,

Thanks for getting in touch! Absolutely, that looks great! The more options our users have, the merrier. It will probably be a few weeks until we have time to implement it, but we're looking forward to it!

Best Max
