Researchers have characterized the feasible set of value functions in partially observable Markov decision processes (POMDPs) as a semi-algebraic set. This extends previous work on fully observable processes, revealing that partial observability introduces nonlinear constraints and a more complex geometric structure. The findings offer new insights into policy optimization and highlight unique phenomena in POMDPs, such as the potential for isolated local reward maximizers. AI
