gym-gridverse - Custom Gridworld Environments for Reinforcement Learning

Gridworld domains for fully and partially observable reinforcement learning.

GridVerse is highly customizable; while many components are provided out-of-the-box, it is designed such that you can create your own components programmatically, including your own objects, starting states, transition functions, reward functions, observation functions, terminating functions, etc.

gym-pomdps - Gym Environments for Flat POMDPs

Gym environments for POMDPs and DecPOMDPs respectively encoded by .POMDP and .DPOMDP files.

Available at abaisero/gym-pomdps.

rl-parsers - Reinforcement Learning Parsers

Parsers for file formats related to reinforcement learning, including the standard .MDP, .POMDP and .DPOMDP file formats, and the custom .FSC (Finite State Controller) and .FSS (Finite State Structure) file formats.

Available at abaisero/rl-parsers.

one-to-one - Tools for Semantic Indexing

Tools for flat indexing of complicated semantic structures.

Family of classes which represent bijections between sets of \(N\) structured and/or semantic values/objects and a corresponding set of indices \({0, \ldots, N-1}\); Useful to represent and access tables of values indexed directly by objects with rich interfaces and attributes.

The provided classes automate (via a user-friendly interface) the conversions between values and indices.
