Sentence Examples:
• This does not mean that the method should be heuristic in Rousseau's sense, that the child should be told nothing, but be left to rediscover all knowledge for himself.

• There are no leading strings to interfere with the independence of one's progress. But this self-activity is increased, if the guide—to keep up the simile—lets go the hand of his companion, because the latter, with the goal in sight, is so sure of foot as to need no further assistance.

Why This Word:

Heuristic methods are used to speed up the process of finding a good enough solution, where an exhaustive search is impractical. Examples of this method include using a "rule of thumb", an educated guess, an intuitive judgment, or common sense. In more precise terms, heuristics are strategies using readily accessible, though loosely applicable, information to control problem solving in human beings and machines.
