If algorithms guarantee problem solutions, why do people ever use heuristics, which do not?
A)Sometimes no algorithm is available to solve a particular problem.
B)Heuristics often require less time and effort to apply than do algorithms.
C)Heuristics produce successful problem solutions with sufficient frequency to justify their use.
D)People use heuristics for all these reasons.

People use heuristics for multiple reasons including when an algorithm is not available, when heuristics require less time and effort than algorithms, and when heuristics have been observed to produce successful problem solutions with acceptable frequency. Therefore, all the options listed in the answer choices are valid reasons why people may choose to use heuristics over algorithms.
