New method accelerates optimization with uncertain inputs

Researchers have developed a new method called Phenotype-Accelerated Evolutionary Strategy (PAES) to improve optimization processes when inputs are uncertain. This technique leverages the information from realized inputs, which is often discarded in existing approaches, to reduce the variance of gradient estimators through Rao-Blackwellization. Theoretical analysis and numerical experiments demonstrate that PAES converges faster than standard Evolutionary Strategy (ES) on various optimization problems, including reinforcement learning benchmarks.
