SARSOP

This Julia package wraps the SARSOP software for offline POMDP planning. It works with the POMDPS.jl interface. A module for writing POMDPX files is provided through the POMDPXFile.jl package, and is a dependency for SARSOP.jl.

For a pure Julia implementation that avoids the pomdpx file bottleneck, see NativeSARSOP.

Installation

It is recommended that you have POMDPs.jl installed. To install SARSOP and its Julia wrapper run the following command:

] add SARSOP

Example Usage

using POMDPs
using SARSOP
using POMDPModels

pomdp = TigerPOMDP()
solver = SARSOPSolver()
policy = solve(solver, pomdp)
