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.

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

] add SARSOP

using POMDPs
using SARSOP
using POMDPModels

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

Detailed documentation can be found here.

The supporting SARSOP_jll package was created using BinaryBuilder.jl. The build_tarballs.jl script can be found on Yggdrasil, the community build tree. To update and build new binaries:

• Modify the JuliaPOMDP fork of SARSOP (https://github.com/JuliaPOMDP/sarsop)
• Fork and update the Yggdrasil SARSOP_jll build_tarballs.jl script
• Create a pull request on JuliaPackaging/Yggdrasil
• Update this README with the correct links

SARSOP.jl uses the APPL library.
