Moore machine is a finite state machine in which the next state is decided by the current state and the current input symbol.The output symbol at a given time depends only on the present state of the machine.The Moore machine has 6 tuples(Q, q0, Σ, O, δ, λ)Where, Q: Finite ... Read More

In a mealy machine, the output symbol depends upon the present input symbol and on the present state of the machine.The output is represented with each input symbol and each state is separated by /.The mealy machine can be described by 6 tuples(Q, q0, Σ, O, δ, λ')Where, Q: Finite ... Read More

Non-deterministic finite automata also have five states which are same as DFA, but with different transition function, as shown follows −δ: Q X Σ -> 2QNon-deterministic finite automata is defined as a 5 tuple, M=(Q, Σ, δ, q0, F)Where, Q: Finite set of statesΣ: Finite set of the input symbolq0: ...

NFA stands for non-deterministic finite automata. It is easy to construct an NFA when compared to DFA for a given regular language.The finite automata are called NFA when there exist many paths for specific input from the current state to the next state.Each NFA can be translated into DFA but ...

A Deterministic Finite automata (DFA) is a collection of defined as a 5-tuples and is as follows −M=(Q, Σ, δ, q0, F)Where, Q: Finite set called states.Σ: Finite set called alphabets.δ: Q × Σ → Q is the transition function.q0 ∈ Q is the start or initial state.F: Final or ... Read More

DFA refers to deterministic finite automata. Deterministic refers to the uniqueness of the computation. The finite automata are deterministic FA, if the machine reads an input string one symbol at a time.In DFA, there is only one path input from the current state to the next state. It does not ...
