Optuna c-TPE generalized as joint density estimator

A new paper introduces the Optuna Constrained Tree-Structured Parzen Estimator (c-TPE) as a joint density generalization of the standard c-TPE algorithm. This formulation, referred to as joint c-TPE, utilizes a single joint likelihood for both the objective and constraints, offering advantages over approaches that assume independence. The research highlights that joint c-TPE is invariant to constraint duplication, unlike the independent c-TPE which can degrade with such redundancies, and discusses practical trade-offs and future research directions.
