Скачать или смотреть CFG → CNF Made Easy | Why We Need Normal Forms

In this video, we start our journey from Context-Free Grammar (CFG) to Chomsky Normal Form (CNF) and also introduce Greibach Normal Form (GNF).
You’ll first understand why we need normal forms, using an intuitive derivation tree explanation, and then see how we’ll proceed from CFG to CNF through a step-by-step approach.

📘 What You’ll Learn:

Why we use normal forms in grammar simplification

Overview of CNF and GNF

Preconditions before CNF conversion:
✅ Null (ε) Production Removal
✅ Useless Symbol Removal
✅ Unit Production Removal

Small examples for each step

A clear roadmap for CFG → CNF conversion

🎯 Ideal for:
Students learning Automata Theory, Formal Languages, or Compiler Design — this video builds the foundation for CNF conversion in the simplest way possible.
