navigation-mdp 0.4

A lightweight library for defining navigation grid world

Navigation MDP

A bare-bones Python3 interface for specifying navigation mdp. Designed to provide more natural syntax to specify MDP while also providing some extensibility required for experimentation.

Markov Decision Process (MDP)

MDP is defined by states S, dynamics T, actions A, and rewards R. The design philosophy of this library is that each entity in the MDP is a separate object. State is the central entity. Everything else is optional, and can be defined and attached to the states as per the need.
