strategy
n. a program of action designed to achieve a goal or accomplish a task. The term is used in a variety of contexts. For example, in artificial intelligence, it denotes a specific approach used for designing searches of a problem or game space. Strategies in this sense are used to determine which state in the search is to be considered next and are often called heuristics. In biology, however, the term refers to an approach for ensuring reproductive success, as in a K-strategy or an r-strategy.
