POMDPs.jl

A Julia interface for defining, solving and simulating partially observable Markov decision processes and their fully observable counterparts.

Package and Ecosystem Features

  • General interface that can handle problems with discrete and continuous state/action/observation spaces
  • A number of popular state-of-the-art solvers implemented for use out-of-the-box
  • Tools that make it easy to define problems and simulate solutions
  • Simple integration of custom solvers into the existing interface

Available Packages

The POMDPs.jl package contains only the interface used for expressing and solving Markov decision processes (MDPs) and partially observable Markov decision processes (POMDPs). The POMDPTools package acts as a "standard library" for the POMDPs.jl interface, providing implementations of commonly-used components such as policies, belief updaters, distributions, and simulators. The list of solver and support packages maintained by the JuliaPOMDP community is available at the POMDPs.jl Readme.

Documentation Outline

The documentation is organized into three sections:

1. Examples and Tutorials–Practical, step-by-step demonstrations are provided in the Examples and the Gallery of POMDPs.jl Problems, illustrating common workflows and use cases.

2. API Reference–Complete technical documentation of all interface functions, types, and methods in POMDPs.jl can be found in the API Documentation.

3. Explanatory Guide–Conceptual explanations of POMDPs.jl, including how to define problems, solve them using provided solvers, and simulate results. See the detailed sections listed below.
