What is the difference between DFA and NFA?
DFA stands for Deterministic Finite Automaton NFA stands for Non-Deterministic Finite AutomatonWhen processing a string in a DFA, there is always a unique state to go next when each character is read. It is because for each state in DFA, there is exactly one state that corresponds to eachcharacter being read.In an NFA, several choices (or no choice) may exist for the next state•Can move to more than 1 states, or nowhere•Can move to a state without reading anything1. The transition function for nfa ie delta is multi valued where as for dfa it is single valued.2. Checking membership is easy with dfa where as it is difficult for nfa3. Construction of nfa is very easy where as for dfa it is difficult4. Space required for dfa is more where for nfa it is less5. Backtracking is allowed in dfa,but it is not possible in every casi in nfa.6. For every input and output we can constuct dfa machine,but it is not possible to construct an nfa machine for every input and output.7. There is only 1 final state in nfa but there can be more then 1 final state in dfa.A finite automata, in which after consuming an input symbol, automata makes it's transition to only one state, is called as the deterministic finite automata or DFA. p(current state)----->input symbol------> state q(next state)A finite automata, in which after consuming an input symbol, automata can make it's transition more one state, is called as the nondeterministic finite automata or NFA.p(current state)----->input symbol------> state q(first guessing)--->state r( next guessing)i.e. a nfa can guess the next states and if any guess proves to be right later than it get stuck and continue with other guesses.
What is convergent sequence?
A convergent sequence is an infinite sequence whose terms move ever closer to a finite limit. For any specified allowable margin of error (the absolute difference between each term and the finite limit) a term can be found, after which all succeeding terms in the sequence remain within that margin of error.
What are the differences between finite and infinitete verb?
A finite verb is a verb that has a complete meaning eg I am dancing.while an infinite verb is a verb that deosn't have a complete meaning eg dancing.
What is the difference of finite and infinite?
its 2 types of numbers Finite numbers: have an end. they can be extremely long, but as long as they have an end at some point they are finite Infinite numbers never end. 1/3 is infinite, because the 0,3333 continues forever without even reaching exactly 1/3. 1/4 is finite, because it is exactly 0,25. So basically infinite numbers can never be written down exactly (in a decimal way), no matter how much paper you use, whereas finite numbers can.
The set of all counting numbers less than one million is it finite or infinite?
Finite.
Difference between deterministic finite automata and non deterministic finite automata?
A deterministic finite automaton will have a single possible output for a given input. The answer is deterministic because you can always tell what the output will be. A nondeterministic finite automaton will have at least one input which will cause a "choice" to be made during a state transition. Unlike a DFA, one input can cause multiple outputs for a given NFA.
Difference between deterministic finite automaton and non deterministic finite automaton?
The state machine described in the previous section is a deterministic finite automaton, in which each state is unique. What would make a finite automaton nondeterministic is if each state was not. For the example, if the state machine allowed the input to have any letter as the second letter for the word "person" to transition to the next, then the next state would not be unique, making it a nondeterministic finite automaton.
What is relation between regular languages finite automaton and regular grammars?
finite automaton is the graphical representation of language and regular grammar is the representation of language in expressions
What is a biautomaton?
A biautomaton is a finite automaton which arbitrarily alternates between reading the input from the left and from the right.
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.
Why a finite automaton is called finite?
I would guess that is because it has a finite number of different states. (It is also known as a finite-state machine.)
Distinguish between dfa and nfa?
DFA stands for Deterministic finite automaton and NFA stands for Nondeterministic finite automaton.Formally, an automaton is made up of: were delta is the transition function. In a DFA, delta takes as input a state and letter and returns only one state. In an NFA, delta takes as input a state and letter but returns a set of states.An NFA accepts a word iff there exists a run of the automaton on it (intuitively, the automaton guesses an accepting run). A DFA has only one run on every word and therefore accepts a word iff the single run on it is accepting.
What is the definition of a buchi automaton?
A Buchi automaton is a regular automaton but reads infinite words instead of finite words. A word is defined to be in the language of the automaton iff a run of the automaton on it visits inifinitly many times in the group of final states (or receiving states).
What did nfa stand for?
NFA - Non-deterministic Finite Automaton, aka NFSM (Non-deterministic Finite State Machine)
What is the difference between finite and non finite?
finite is an object , and they are also singular in nature
Difference between finite automata and turing automata or turing machine?
A push down automaton can actually store information in a stack as it processes it. It can then choose what to do next by looking at the top of the stack. DFAs and NFAs can't do that stuff, but any DFA or NFA can also be represented as a push down automaton.
What is the Difference between a finite set and countable set?
all finite set is countable.but,countable can be finite or infinite
