In formal language theory, a Context-free grammar (CFG) is a certain type of formal grammar: a set of production rules that describe all possible strings in a given formal language. Production rules are simple replacements. For example, the rule* * * * A * * → * * α * * * {\displaystyle A\ \to \ \alpha } * * replaces * * * * A * * * {\displaystyle A} * with * * * * α * * * {\displaystyle \alpha } * . There can be multiple replacement rules for any given value. For example, * * * * * A * * → * * α * * * {\displaystyle A\ \to \ \alpha } * * * * * * A * * → * * β * * * {\displaystyle A\ \to \ \beta } * * means that * * * * A * * * {\displaystyle A} * can be replaced with either * * * * α * * * {\displaystyle \alpha } * or * * * * β * * * {\displaystyle \beta } * . * In context-free grammars, all rules are one-to-one, one-to-many, or one-to-none. These rules can be applied regardless of context. The left-hand side of the production rule is always a nonterminal symbol. This means that the symbol does not appear in the resulting formal language. So in our case, our language contains the letters * * * * α * * * {\displaystyle \alpha } * and * * * * β * * * {\displaystyle \beta } * but not * * * * A * . * * * {\displaystyle A.} * Rules can also be applied in reverse to check if a string is grammatically correct according to the grammar. * Here is an example context-free grammar that describes all two-letter strings containing the letters * * * * α * * * {\displaystyle \alpha } * and * * * * β * * * {\displaystyle \beta } * . * * * * * S * * → * * A * A * * * {\displaystyle S\ \to \ AA} * * * * * * A * * → * * α * * * {\displaystyle A\ \to \ \alpha } * * * * * * A * * → * * β * * * {\displaystyle A\ \to \ \beta } * * If we start with the nonterminal symbol * * * * S * * * {\displaystyle S} * then we can use the rule * * * * * S * * → * * A * A * * * {\displaystyle S\ \to \ AA} * to turn * * * * S * * * {\displaystyle S} * into * * * * A * A * * * {\displaystyle AA} * . We can then apply one of the two later rules. For example, if we apply * * * * A * * → * * β * * * {\displaystyle A\ \to \ \beta } * to the first * * * * A * ... |
