In video game AI, a utility system, or utility AI, is a simple but effective way to model behaviors for non-player characters. Using numbers, formulas, and scores to rate the relative benefit of possible actions, one can assign utilities to each action. A behavior can then be selected based on which one scores the highest "utility" or by using those scores to seed the probability distribution for a weighted random selection. The result is that the character is selecting the "best" behavior for the given situation at the moment based on how those behaviors are defined mathematically.
