Problems on Finite Automata

Finite Automata (FA) are simple machines that help us understand how computers recognize patterns in data. They follow a set of fixed rules and read input step by step to determine if it follows a specific pattern. These machines are commonly used in spell-checkers, search engines, and text-processing programs.

This page offers a collection of simple examples demonstrating how Finite Automata process different inputs:

1. DFA for Strings not ending with “THE”
2. DFA of a string with at least two 0’s and at least two 1’s
3. DFA for accepting the language L = { aⁿb^m | n+m=even }
4. DFA machines accepting odd number of 0’s or/and even number of 1’s
5. DFA of a string in which 2nd symbol from RHS is ‘a’
