Motivation
I want to use EUBO with a previous_winner while also applying a posterior_transform (e.g., a weighted sum).
There were two options:
AnalyticEUBO doesn’t naturally support posterior_transform because it assumes a single‑output preference model, while qEUBO already accepts posterior_transform and can follow the same previous_winner handling as in AnalyticEUBO. So I added previous_winner support in qExpectedUtilityOfBestOption to enable that workflow.
Have you read the Contributing Guidelines on pull requests?
Yes.
Test Plan
I have conducted tests here:
