The defining characteristic of FA is that they have only a finite number of states. Hence, a finite automata can only "count" (that is, maintain a counter, where different states correspond to different values of the counter) a finite number of input scenarios.
There is no finite automaton that recognizes these strings:
- The set of binary strings consisting of an equal number of 1's and 0's
- The set of strings over '(' and ')' that have "balanced" parentheses
The 'pumping lemma' can be used to prove that no such FA exists for these examples.

What is the difference between deterministic finite automata and non deterministic finite automata?
A deterministic Finite Automata)DFA will have a single possible output for a given input.The answer is deterministic because you can always feel what the output will be.A (Nondeterministic Finite Automata)NFA will have at least one input which will cause a "choice" to be made during a state transition,unlike a (deterministic Finite Automata)DFA one input can cause multiple outputs for a given (Nondeterministic Finite Automata)NFA.
Describe how lexical analyzer generators are used to translate regular expressions into deterministic finite automata?
Lexical analyzer generators translate regular expressions (the lexical analyzer definition) into finite automata (the lexical analyzer). For example, a lexical analyzer definition may specify a number of regular expressions describing different lexical forms (integer, string, identifier, comment, etc.). The lexical analyzer generator would then translate that definition into a program module that can use the deterministic finite automata to analyze text and split it into lexemes (tokens).
What are automata in dt?
In the context of discrete mathematics (dt), automata are abstract mathematical models that represent computational systems or processes. They consist of states, transitions between those states, and an input that triggers these transitions, allowing them to process strings of symbols. Automata theory is fundamental in computer science, particularly in designing algorithms, compilers, and understanding formal languages. Common types include finite automata, pushdown automata, and Turing machines, each with varying levels of computational power.

What is finite automata you-moves?
Finite automata with ε-moves, also known as epsilon transitions, are a type of finite state machine that allows transitions between states without consuming any input symbols. This means that the automaton can move from one state to another spontaneously, enabling it to represent a broader range of languages than standard finite automata. Epsilon transitions can simplify the design of automata, particularly when converting from nondeterministic finite automata (NFA) to deterministic finite automata (DFA) or when constructing automata for regular expressions.
What is full form of DFA and NFA?

Are all deterministic finite automata (DFAs) also non-deterministic finite automata (NFAs)?
No, not all deterministic finite automata (DFAs) are also non-deterministic finite automata (NFAs). DFAs have a single unique transition for each input symbol, while NFAs can have multiple transitions for the same input symbol.
Is it possible to show that all deterministic finite automata (DFA) are decidable?
Yes, it is possible to show that all deterministic finite automata (DFA) are decidable.
What is difference between finite state automaton and transition graph?
finite automata
What does dfa stand for?
Deterministic finite state automata
What is dfa and nfa?
DFA - Deterministic Finite Automata NFA - Non-Deterministic Finite Automata Both DFAs and NFAs are abstract machines which can be used to describe languages.
What is better Finite Automata or Regular Expression?
Finite Automata and Regular Expressions are equivalent. Any language that can be represented with a regular expression can be accepted by some finite automaton, and any language accepted by some finite automaton can be represented by a regular expression.
Is it possible to demonstrate that all deterministic finite automata (DFA) are in the complexity class P?
Yes, it is possible to demonstrate that all deterministic finite automata (DFA) are in the complexity class P.
What are objectives of automata theory?
The objectives of automata theory include the formal study of abstract machines and the computational problems they can solve. It aims to define and classify different types of automata, such as finite automata and Turing machines, to understand their capabilities and limitations. Additionally, automata theory provides a foundation for various fields, including computer science, linguistics, and formal verification, by offering tools for analyzing and designing algorithms, programming languages, and computational systems.
What you mean by Finite Automata?
Finite automata are machines used to recognize patterns from input set of characters. They either reject or accept inputs based on the already defined pattern set by the FA.
