shop3
An open-source Hierarchical Task Network (HTN) AI planner written in Common Lisp, supporting PDDL and HDDL.
What is shop3?
SHOP3 is an open-source Hierarchical Task Network (HTN) AI planner written in Common Lisp. It solves complex planning problems by decomposing high-level tasks into executable actions, supporting standard planning languages like PDDL and HDDL for domain modeling and plan generation.
AI researchers, developers, and students working on automated planning, task decomposition, or reasoning systems, particularly those using Common Lisp or requiring integration with PDDL/HDDL standards.
Developers choose SHOP3 for its robust HTN planning capabilities, strong support for PDDL and HDDL standards, and reliability across multiple Common Lisp implementations, backed by extensive testing and active maintenance.
