We have created a number of software packages that are available as open source software:

• OscaR: constraint programming in Scala
• MiniCP: lightweight constraint programming in Java
• MaxiCP: constraint programming in Java
• CP-Model-Zoo (online tool): automatic retrieval of CP models using NLP queries
• CP4DM: constraints for data mining in OscaR
• DDO: generic and efficient framework for MDD-based optimization in Rust
• DDOLib: generic and efficient framework for MDD-based optimization in Java
• DL8.5: exact decision trees in C++ with Python API
• PyTrees-Rs: exact decision trees in Rust with a Python API
• Orthanc: free and open-source ecosystem for medical imaging (DICOM)
