Discussion
The Chess Master selects his next move by considering moves that would threaten his opponent's queen. His opponent, a chess-playing computer selects its next move by considering all possible moves. The chess master is using _____ and the computer is using _____.
Answer: D
The chess master uses a heuristic and the computer uses an algorithm.
A heuristic is a rule of thumb that narrows the search, as when the master considers only moves that threaten the queen. An algorithm is a step-by-step method that guarantees a solution by trying every possibility, as the computer does when it considers all possible moves.
The other options reverse the pair or bring in a prototype or mental set, which are not problem-solving procedures of this kind.
