#snsinstitutions #snsdesignthinkers #designthinking In this video, you will learn the formal definition of a Non-deterministic Finite Automaton (NFA), one of the fundamental concepts in the Theory of Computation. The session begins by introducing the formal representation of an NFA using the five-tuple notation (Q, Σ, δ, q₀, F) and explains the purpose of each component in recognizing regular languages. The video also covers the notations used in NFA, providing a clear understanding of states, input symbols, transition functions, start state, and accepting states. You will learn how the transition function (δ) differs from that of a DFA by allowing multiple possible next states for a given input symbol. Furthermore, the session demonstrates how to represent an NFA using a transition diagram, making it easy to visualize state transitions and non-deterministic behavior. It also explains how to construct and interpret an NFA transition table, enabling learners to analyze and design NFAs systematically. By the end of this video, you will be able to:
