SARISA

Build Status Coverage Status

This Julia package is a wrapper for my modified APPL code that solves rho-POMDPs.

Installation

At the Julia command prompt, run:

] add https://github.com/sisl/SARISA.jl

Running the Code

The code can be called as follows:

sarisa(pomdpx_file::String, timeout::Real=30, variant::String="MN"; filename="temp.policy")`

The timeout is expressed in seconds. There are three main variant strings:

  • MN Max-norm reward function.
  • GU Guess reward function.
  • TH_90 Threshold reward function with cutoff at ||b||_inf = 0.9.

There are two more allowed variant strings, but these use the unimproved lower bound. The only reason they are included is to show the value of using my improved lower bound.

  • MB Max-norm with bad (unimproved) lower bound.
  • TB_90 Guess reward function with bad (unimproved) lower bound.

The resulting policy file is saved to filename.
