Structured configuration spaces (non-scalar variables)?

No, we currently don't have that. Could you please give an example use case? And is this similar to #122?

Structured configuration spaces (non-scalar variables)?

Thanks a lot for the explanation. Unfortunately, the design of the ConfigSpace doesn't lend itself for easily implementing this. If you have an idea how to do so, please let...

Allow for hyperparameter sampling without an explicit random state required.

I usually use https://github.com/automl/ConfigSpace/blob/master/scripts/benchmark_sampling.py to benchmark changes. Probably we should improve that script and document how to use it.

Generate neighbors and sample configurations correctly with deeply nested conditions

Hi @dengdifan and @filipbartek, Please excuse the delay, but I finally get to your two PRs (this one and #219). As a first step I checked, and they both fix...

Generate neighbors and sample configurations correctly with deeply nested conditions

We need to check if this PR fixes https://github.com/automl/ConfigSpace/issues/196 as well.

Generate neighbors and sample configurations correctly with deeply nested conditions

Hi @filipbartek, thank you very much for your explanation. As discussed, I just merged #219. Could you please rebase your PR, I will then check again how to proceed.

One-exchange neighborhood may raise `ValueError` non-deterministically

Thanks a lot for reporting this. Would you mind creating a pull request fixing this? What worries me a bit more, though, is that this is actually triggered - this...

One-exchange neighborhood may raise `ValueError` non-deterministically

Thanks a lot for the PR and the additional example. So apparently there is an issue in the neighborhood generation that leads to the creation of invalid configurations. If you...

One-exchange neighborhood may raise `ValueError` non-deterministically

Re-opening this as #195 only solves half of this issue.

`Configuration.get()` always return None if key is not in CS regardless of the provided default value

Thank you very much for reporting this. I can confirm this issue. I just tried to fix it, however, this results in an endless loop when requesting new neighbors from...
