Which concept captures the idea of evaluating moves under the assumption of optimal counter-moves by the opponent?

• A. Lack of Understanding
• B. Recursion
• C. Adversarial Search
• D. Binary Search

Answer: (C)

Adversarial search is the idea of evaluating moves under the assumption that the opponent will respond with optimal moves. In games, you model both players, exploring a tree of possible moves and counter-moves, and you choose the option that yields the best outcome even when the opponent tries to minimize it. This is typically done with minimax reasoning, where you assume the opponent will pick the path that minimizes your payoff on each turn, and you pick the move that maximizes your eventual outcome. Alpha-beta pruning is a common optimization, but the core is reasoning about an adversary. Lack of Understanding isn’t about strategic planning against an opponent. Recursion is a programming technique used to traverse the game tree, not the concept of opponent modeling itself. Binary Search is a method for quickly locating items in a sorted list and has no relevance to adversarial reasoning.
