Arc consistency look ahead also checks whether the values of x 3 and x 4 are consistent with each other (red lines) removing also the value 1 from their domains. A look-ahead technique that may be more time-consuming but may produce better results is based on arc consistency. Namely, given a partial solution extended with a value for a new ...
series) is a product line of how-to and other reference books published by Dorling Kindersley (DK). The books in this series provide a basic understanding of a complex and popular topics. The term "idiot" is used as hyperbole, to reassure readers that the guides will be basic and comprehensible, even if the topics seem intimidating.
