Specify lower bound of `L_max` about dynesty

[segasai]

I am not sure I see what problem specifically that would solve, so I'm not enthusiastic in the outset.

If you want to sample a tiny volume around the maximum you can always specify the prior be around it.

Thanks, the point is not to sample around the maximum; rather: can knowledge of the MLE help the sampler? If so, how can we provide this to the sampler?

[segasai]

In the way the current sampler is written, there is no way to use that information . I.e. all the decisions for the sampler are based on the current set of live-points.
It is certainly possible to provide the MLE point as one of the initial set, but that will break the assumptions of the sampler (that points are sampled from the prior).
I was considering in the past the possibility of using all the likelihood evaluation locations (i.e. even rejected points to decide on ellipsoidal bounds), but I never implemented it.

[dilpath]

Ah, from optimization at least, there would be many points in addition to the MLE that could be supplied.

Anyway, thanks for your answer!
