Forward and backward reasoning
WebBackward Chaining, also known as backward reasoning, is an inference engine reasoning technique that begins with a hypothetical goal. Backtracking is used to find the most optimal way to resolve a conflict or reach a goal state, where the search begins at the conclusion and goes back to understand the conditions that led to the conclusion.
