Abstract: Partially observable Markov decision processes (POMDPs) have
recently become popular among many AI researchers because they serve
as a natural model for planning under uncertainty. Value iteration is
a well-known algorithm for finding optimal policies for POMDPs. It
typically takes a large number of iterations to converge. This paper
proposes a method for accelerating the convergence of value iteration.
The method has been evaluated on an array of benchmark problems and
was found to be very effective: It enabled value iteration to converge
after only a few iterations on all the test problems.
