In this lecture, we begin Part 1 of the Simplification of Context-Free Grammar (CFG) by focusing on the Elimination of Useless Symbols, Non-Reachable Symbols, and Non-Generating Symbols.
🔹 What You’ll Learn:
✅ What are Useless Symbols? – Understanding why certain symbols do not contribute to language generation.
✅ Elimination of Non-Reachable Symbols – Removing symbols that are never reached from the start symbol.
✅ Elimination of Non-Generating Symbols – Identifying symbols that never derive a terminal string.
✅ Step-by-Step Process of Eliminating Useless Symbols – Simplifying a CFG by systematically removing unnecessary components.
This video is essential for students and professionals studying Theory of Computation (TOC), Automata Theory, and Context-Free Grammar (CFG).
