STRIPS-style planning

This is a precursor to MDP planning:

  • states: conjunction of “fluents” (which are state)
  • actions: transition between fulents
  • transitions: deleting of older, changed parts of fluents, adding new parts

Planning Domain Definition Language

A LISP used to specify a STRIPS-style planning problem.

Hierarchical Task Network

  1. Decompose classical planning into a hierarchy of actions
  2. Leverage High level actions to generate a coarse plan
  3. Refine to smaller problems
