Compact Policies for Submodular MDPs via LP-Based Submodular Orienteering

A new arXiv paper introduces an approach for deriving strong yet compact action-selection policies in Markov Decision Processes whose value functions are submodular. The method builds on a linear-programming formulation of submodular orienteering, a problem where an agent must reach a set of targets under a budget. The authors argue this yields policies that are both effective and compact, relevant to reinforcement learning and operations research settings where repeated action choice is required.

arXiv paper studies Fisher-Rao gradient flows of linear programs and natural policy gradients

A revised arXiv preprint analyzes natural gradient methods built on the Fisher information matrix of the state-action distribution. The authors connect these methods to Fisher-Rao gradient flows of linear programs, aiming to clarify why Kakade-style natural policy gradient updates converge, including in regularized settings. The work is theoretical and sits at the intersection of optimization and reinforcement learning.
