Understanding DFA in Theory of Computation with Examples 🤖

There is a single (unique) transition from one state to other with a single input alphabet, then that Automata is called as Deterministic Finite Automata (DFA). In DFA, each and every state should contain exactly one out degree for each input symbol of alphabet. It is represented as 5 tuples. M = (Q, 𝜮, 𝜹, qo, F) Where, Q → Set of finite states 𝜮 → Set of input alphabet qo → Initial state F → Set of final states 𝜹 → Transition function or mapping functions defined as 𝜹: Q × 𝜮 → Q Consider the following example: DFA for starting with a over 𝛴 = {a,b} Representation of DFA: Transition diagram: Q = {A, B, C} qo = A F = { B } 𝛴 = { a,b} Transition function: 𝜹: Q × 𝜮 → Q 𝛿(𝐴, 𝑎) → 𝐵, 𝛿(𝐴, 𝑏) → 𝐶 𝛿(𝐵, 𝑎) → 𝐵 , 𝛿(𝐵, b) → 𝐵 𝛿(𝐶, 𝑎) → 𝐶 , 𝛿(𝐶, 𝑎) → C ⭐ Courses Playlist ⭐ 🔗 THEORY OF COMPUTATION https://www.youtube.com/playlist?list=PLS6nugESt9lL2Ty58dt59vjwqID4k8v2H 🔗FUZZY SET: https://www.youtube.com/playlist?list=PLS6nugESt9lLeVTXWMD_NXNVAKAC8RYDg 🔗SYSTEM PROGRAMMING (SP): https://www.youtube.com/playlist?list=PLS6nugESt9lIGSB_qxapdJh46j_5Hwhlq 🔗COMPILER DESIGN | COMPILER | LANGUAGE PROCESSOR: https://www.youtube.com/playlist?list=PLS6nugESt9lLXiC2WFznm4Gly6dykw5Oo 🔗DESIGN AND ANALYSIS OF ALGORITHMS (DAA)| ALGORITHM: https://www.youtube.com/playlist?list=PLS6nugESt9lJ2rluFZTYq8YnpRD1rm5Wf 🔗Computer Architecture and Digital System: https://www.youtube.com/playlist?list=PLS6nugESt9lKerCOnI48acy6hwmEJvtEG 🔗COMPUTER GRAPHICS (CG) BY.
