Which search method uses a rule of thumb to decide which option to explore first?

• A. Binary Search
• B. Lack of Understanding
• C. Frame Problem
• D. Heuristic Search

Answer: (D)

Using a rule of thumb to decide which option to explore first is exactly what a heuristic search does. A heuristic provides a quick, practical rule to estimate which paths look most promising, guiding the search to expand those options first and often reaching a solution faster in large or complex spaces. This contrasts with a precise algorithm like binary search, which relies on exact, deterministic steps (splitting the search space in half) rather than a flexible guess about where to go next. The frame problem is a broader AI concept about representing and updating knowledge in changing situations, not a strategy for choosing exploration order. Lack of Understanding isn’t a search method at all. So the best fit for a method that uses an internal rule of thumb to prioritize exploration is heuristic search.
