Intentional randomness is totally different from Uniformed Randomness. Intentional randomness occurs in nature in situations when establishing a clear pattern will hurt rather than help an organism. For instance, is you're being chased by a lion through the jungle, it is considerably more advantageous for you to twist and turn randomly rather than run in a straight line. The same holds true for computerized enemies in computer games. If you're programming an aviation game with a dog-fighting sequence, you're going to want the computer to behave randomly and unexpectedly at times, in order to prevent a human opponent from being able to recognize a pattern and anticipate the computer's next move.
