Releases: xopt-org/Xopt
v2.6.1
Note:
This PR changes default modeling behavior of Gaussian Process models to be preferential towards noisy objectives. For working in noiseless environments please change generator.gp_constructor.use_low_noise_prior = True. See the Xopt documentation for examples.
What's Changed
- Fix VOCS/MOBO validation issues and improve handling by @nikitakuklev in #304
- Add BAX in the automated API documentation by @RemiLehe in #305
- Change default for use low noise prior by @roussel-ryan in #306
- Turbo documentation by @roussel-ryan in #308

v2.6.0
This release makes major changes to several generator types, including introducing the SequentialGenerator class that serves as a base class for generators that do not allow for data to be added to them from outside the optimization loop. The following generators now inherit from this class:
RCDSGeneratorExtremumSeekingGeneratorNelderMeadGenerator
Additionally, thanks to @electronsandstuff we also introduce the DeduplicatedGeneratorBase that prevents generators from proposing previously proposed points in parameter space. This has been incorporated into the following generators:
CNSGAGeneratorNSGA2Generator(new!)
We have also implemented stricter checking of vocs when passed to Xopt generator objects. Passing invalid vocs to generators (e.g. passing vocs with constraints to a generator that cannot account for constraints) will now raise a validation error. Those looking to implement their own generators will now need to explicitly set flags that confirm which types of optimization problems a given generator can handle (see flags in the base generator class).
Finally, thanks to @nikitakuklev for identifying and correcting several important bugs in algorithm logic.
