Planning Domain Definition Language is used to define planning domain models used by AI Planning engines. Use this pddl tag for questions about:

  • modeling in PDDL and understanding of the syntax,
  • parsing PDDL models,
  • interpreting constructs the PDDL syntax allows and about
  • widely used tools such as VAL/Validate, or well known planner implementations.

For getting started, learning from examples or trying out AI Planning without installing anything, visit http://planning.domains/, where the AI planning community centralizes such resources. For more advance work and certainly when working on industrial applications, or your own planning engine implementation, it is convenient to use VS Code with PDDL Extension. These resources and tools guide the novice and empower the expert, thus provide the answer before you realize you had a question.
