Center hyperedge (induced by source paper "planning with partially observable markov decision processes advances in exact solution method"):
  Abstract: There is much interest in using partially observable Markov decision processes (POMDPs) as a formal model for planning in stochastic domains. This paper is concerned with finding optimal policies for POMDPs. We propose several improvements to incremental pruning, presently the most efficient exact algorithm for solving POMDPs.

Includes members:
  Member "incremental pruning a simple fast exact method for partially observable markov decision processes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "optimizing sequential medical treatments with auto encoding heuristic search in pomdps")
  Member "a model approximation scheme for planning in partially observable stochastic domains":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a method for speeding up value iteration in partially observable markov decision processes")
