5. Chomsky Normal Form Algorithm to make parsing a string easier
6. Cocke–Younger–Kasami Parsing algorithm using a CFG
7. Earley Parser algorithm for parsing strings that belong to a given context-free language
8. LL parser a top-down parser for a restricted context-free language

Big thanks to all these wonderful repos.
