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 ...
Lookahead or Look Ahead may refer to: A parameter of some combinatorial search algorithms , describing how deeply the graph representing the problem is explored A parameter of some parsing algorithms ; the maximum number of tokens that a parser can use to decide which rule to use
The "(1)" denotes one-token lookahead, to resolve differences between rule patterns during parsing. Similarly, there is an LALR(2) parser with two-token lookahead, and LALR( k ) parsers with k -token lookup, but these are rare in actual use.

The Canonical LR constructs full lookahead sets. LALR uses merge sets, that is it merges lookahead sets where the LR(0) core is the same. The SLR uses FOLLOW sets as lookahead sets which associate the right hand side of a LR(0) core to a lookahead terminal. This is a greater simplification than that in the case of LALR because many conflicts ...
