(As far as I can tell there is very little, if any, difference between this and backward induction in game theory, but I’ve heard several in the community call this “backchaining” recently and so use that term here.)
They’re different. Backward induction starts with all possible end states, and then looks at all 2nd-to-last states and “solves” those by looking at what action is best; then looks at all possible 3rd-to-last states and “solves” those by choosing the action leading to the best 2nd-to-last state, and so on until you’ve solved the entire game.
