What is a relaxed planning problem?

  • A.The original problem with the delete effects ignored
  • B.A version of the problem with fewer objects in the domain
  • C.The problem with the goal weakened to a simpler condition
  • D.A problem solved approximately rather than exactly

Answer: A

Dropping the negative effects means nothing ever becomes false, so the relaxed problem is solvable in polynomial time and its solution length is an admissible estimate. That single idea produced the heuristics that revived forward search. Fewer objects, weaker goals and approximation are different simplifications. Deriving a heuristic from a relaxation whose optimal solution is cheap to compute is the same recipe used throughout heuristic search.
