[Feature Request] Acquisition Functions for Top-K Estimation

[Ryan-Rhys]

🚀 Feature Request

Acquisition function implementation for the task of top-k estimation with diversity as per the following paper:

https://arxiv.org/pdf/2210.01383.pdf

Motivation

Top-k estimation (estimating a set of k optimal designs under a penalty that encourages diversity) is an important task in applications such as virtual screening for drug discovery and materials design.

Additional context

@sangttruong is prepared to open a PR for his implementation.
