Rational Behavior

• Always doing what is expected to maximize goal achievement given the available information.
• So within your current possibilities.
• Chooses actions which maximize the expected value of the Performance Measure, given the Percept sequence to date.
• Does not necessarily involve thinking (e.g. reflexes)
• Computational limits, unavailability of information, non-determinism make perfect rationality unachievable → thus design best program for given resources
