TL;DR
The video explains how to reduce the number of states in a given Deterministic Finite Automaton (DFA) through step-by-step analysis.
Key Insights
- 🪡 Accessible states need to be identified before reducing the number of states in a DFA.
- 🏛️ Classifying states into final and non-final classes helps in the reduction process.
- 🏛️ Distinguishable classes are identified by comparing the transitions of each state.
- #️⃣ The minimal DFA represents the language of the original DFA with the least number of states.

Questions & Answers
Q: What is the first step in reducing the number of states in a DFA?
The first step is to identify the accessible states, starting from the initial state and tracing the transitions based on input symbols.
Q: How do we classify states into final and non-final classes?
States that lead to a final state are classified as final states, while states that do not lead to a final state are classified as non-final states.
Q: How do we find distinguishable classes in a DFA?
We compare the transitions of each state with the transitions of other classes. If the transitions lead to different final states, the states are classified into different classes.
Q: What is the minimal DFA?
The minimal DFA is the resulting automaton after reducing the number of states. It has the least number of states required to represent the same language as the original DFA.
Summary & Key Takeaways
