Heuristics

Heuristics is, basically, rule of thumb or trial and error. Its a method which helps in solving a problem. Usually, heuristics is used when a problem leads to an answer, which has to be close to correct.

An example of heuristics is walking up a hill, as long as the result increases, and when the result decreases you slow down. You can walk any direction as long as its not down the hill, if you do that then you will reach your destination (summit).

Another example, is used in a doctors office. Using the expert system, the doctor inputs the patients symtoms and an answer will show, which fits in with the patients symtoms (this is used in most doctor surgeries).

The Turing Test




The Turing Test is a test to see if a computer is intelligent.
The test works when one person (collegue) is sitting on one side of a wall, on the other side of the wall there is a computer and there is a person with a computer (patient)...as seen in the above picture
The collegue asks questions (commands) and has to guess who responds, if its the person on the computer or the computer. If the collegue guesses wrong then the computer passes the 'test'.
