Logical Thinking and Artificial Intelligence
Chess position analysis can be used to illustrate the logical thinking. The following board position describes a chess problem which has to be solved with 2 moves.
| a | b | c | d | e | f | g | h | ||
| 8 | 8 | ||||||||
| 7 | 7 | ||||||||
| 6 | 6 | ||||||||
| 5 | 5 | ||||||||
| 4 | 4 | ||||||||
| 3 | 3 | ||||||||
| 2 | 2 | ||||||||
| 1 | 1 | ||||||||
| a | b | c | d | e | f | g | h | ||
The white has several options to make a move and checkmate the black. The move Rd5 × Rd7 or Rf7 × Rd7 will immediately provide material advantage to white. There are similar moves which capture pieces and provide immediate material advantages to the white. But a knight move Nc6 which does not provide any material advantage, provides a solution for checkmate for black in two moves.
| .. | Nc6 | |||
| 1 | ... | Kxf7 | 2 | g8Q++ |
| 1 | ... | Kxd5 | 2 | Qa2++ |
| 1 | ... | Rdxd5 | 2 | Re7++ |
| 1 | ... | Rfxd5 | 2 | Rf6++ |
| 1 | ... | Rdxf7 | 2 | Rd6++ |
| 1 | ... | Rfxf7 | 2 | Re5++ |
This is an example which illustrates the use of logical thinking. The logical thinking in chess progresses by evaluating the immediate material gain in each move. This will result in a solution which will require more number of moves or failure to checkmate. However, the not so obvious move of knight results in a very powerful checkmate. Even though this move does not look logical, it is the solution to 2 move check mate problem. A computer programmed to play chess might miss out some good opportunities if it does a material-based search to find moves. Several attempts have been made to build the powerful chess computers in history. But these chess computers have been defeated by Grandmaster human chess players.

Famous quotes containing the words logical, thinking, artificial and/or intelligence:
“Nature’s law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.”
—Anton Pavlovich Chekhov (1860–1904)
“Proportion ... You can’t help thinking about it in these London streets, where it doesn’t exist.... It’s like listening to a symphony of cats to walk along them. Senseless discords and a horrible disorder all the way.... A concert of Brobdingnagian cats. Order has been turned into a disgusting chaos. We need no barbarians from outside; they’re on the premises, all the time.”
—Aldous Huxley (1894–1963)
“Merely external emancipation has made of the modern woman an artificial being.... Now, woman is confronted with the necessity of emancipating herself from emancipation, if she really desires to be free.”
—Emma Goldman (1869–1940)
“The accidental causes of science are only “accidents” relatively to the intelligence of a man.”
—Chauncey Wright (1830–1875)
