In this lecture, we explain how to convert an Epsilon-Nondeterministic Finite Automaton (ε-NFA) to a Deterministic Finite Automaton (DFA) using the Subset Construction Method, with a detailed step-by-step example.

🔹 What You’ll Learn:
✅ Step 1: Finding Epsilon Closure (ε-Closure)
🔸 Understanding how to compute ε-closure for states in ε-NFA.
✅ Step 2: Finding Transitions on Input Alphabet (∑ = {0,1,2})
🔸 Constructing the transition table for the equivalent DFA.
✅ Step 3: Constructing the DFA Transition Diagram
🔸 Visualizing the state transitions in the converted DFA.
✅ Comparison with Direct NFA to DFA Conversion
🔸 Why ε-NFA to DFA conversion requires ε-closure computation.
✅ Final Conclusion:
🔸 Understanding how Subset Construction Method helps in automata transformation.

This video is essential for students and professionals studying Theory of Computation (TOC), Automata Theory, and Formal Languages.
