Key Concepts

Context-Free Grammar

A context-free grammar (CFG) is a type of formal grammar that consists of a set of production rules used to generate all possible strings in a particular formal language. In such grammars, each production rule replaces a single non-terminal symbol with a string of terminal and/or non-terminal symbols, enabling the construction of complex language structures and serving as the foundation for parsing and derivation processes in computer science.

Derivation Tree

A derivation tree, or parse tree, is a hierarchical tree representation that visualizes the syntactic structure of a string according to a CFG. Each node in the tree represents a symbol from the grammar, with internal nodes corresponding to non-terminals and leaf nodes corresponding to terminal symbols. These trees make explicit the order and application of production rules during the derivation of a string.

Leftmost Derivation

A leftmost derivation is a step-by-step process of applying production rules where, at each step, the leftmost non-terminal in the current expression is replaced. This method provides a systematic way to derive strings from a grammar and is particularly useful for constructing parse trees and implementing top-down parsing algorithms.

Rightmost Derivation

A rightmost derivation is analogous to a leftmost derivation, but in this case the rightmost non-terminal in the current expression is replaced at each step. This approach is commonly used in bottom-up parsing and is an alternative perspective to understanding how a CFG generates strings, offering insights into different parsing strategies.
