[edit] Parsing Algorithm list

• Converts NFA to DFA
• Lexical Analyzer
• Recursive descent parser: A top-down parser suitable for LL(k) grammars
• LL parser: A relatively simple linear time parsing algorithm for a limited class of context-free grammars
• LR parser: A more complex linear time parsing algorithm for a larger class of context-free grammars. Variants:
  • Operator-precedence parser
  • SLR (Simple LR) parser
  • LALR (Look-ahead LR) parser
  • Canonical LR parser
• Packrat parser: A linear time parsing algorithm supporting some context-free grammars and parsing expression grammars
• CYK algorithm: An O(n³) algorithm for parsing any context-free grammar
• Earley parser: Another O(n³) algorithm for parsing any context-free grammar
• GLR parser:An algorithm for parsing any context-free grammar by Masaru Tomita. It is tuned for deterministic grammars, on which it performs almost linear time and O(n³) in worst case.
• Inside-outside algorithm: An O(n³) algorithm for re-estimating production probabilities in probabilistic context-free grammars
