What is progression search in planning?

  • A.Searching forward from the initial state towards the goal
  • B.Searching backward from the goal towards the initial state
  • C.Searching the space of partially ordered plans
  • D.Progressively refining an abstract plan into a concrete one

Answer: A

Progression applies actions whose preconditions hold and moves forward through states, which is ordinary state space search with a planning representation. Regression works backwards, partial order planning searches plans rather than states, and refinement is hierarchical planning. Naming the direction of search correctly determines which heuristics apply and what the branching factor will be.
