What is the frame axiom problem that planning representations avoid?

  • A.Stating for every action what it leaves unchanged
  • B.Deciding which frame of reference to describe the world in
  • C.Choosing which fluents to include in the state description
  • D.Determining the boundary of the domain being modelled

Answer: A

Writing an axiom for every combination of action and fluent that is not affected would require a quadratic number of statements, most of them trivial, and the planning representation simply stipulates that unmentioned fluents persist. That stipulation is what makes the formalism concise. Reference frames, fluent selection and domain boundaries are different modelling questions. Adopting a convention that removes a quadratic bookkeeping burden is the single most important design decision in the representation.
