FiMDP - Fuel in Markov Decision Processes
Python Package with Algorithms for Controller Synthesis in Resource-constrained Markov Decision Processes
FiMDP is a Python package for analysis and controller synthesis of Consumption Markov Decision Processes (ConsMDPs) — MDPs with resource constraints. The model of ConsMDPs and the basic algorithms implemented in FiMDP are described in our paper presented at CAV2020 [1].
Our related project called FiMDPEnv is a set of environments that work with FiMDP and can create animations like this one.

Installation
FiMDP can be installed using pip from PyPI
pip install -U fimdp
While the baseline package has minimal dependencies, FiMDP depends on several other tools for extended functionality. Some of the recommended dependencies are:
- Graphviz: for visualizations in Jupyter notebooks,
- Storm and Stormpy: for reading PRSIM, JANI, and Storm models,
- Spot: for support of labeled ConsMDPs and specifications given as deterministic BĂĽchi automata or the recurrence fragment of Linear-time Temporal Logic (LTL).
Usage and documentation (work in progress)
The directory tut contains several notebooks that explain how to use FiMDP. The notebook Basics.ipynb is a good starting point.
For a complete overview of the tool, installation options, source code documentation, and interactive examples refer to FiMDP readthedocs.
Evaluations
Notebooks evaluationg performance of FiMDP are stored in a separate repository FiMDP-Evaluation.
Contact
If you have any trouble with the installation, or have any questions, raise an issue or email František (Fanda) Blahoudek or Pranay Thangeda.
