25-Jul-17 Dr. D. P. Acharjya 2 Non-Deterministic Finite Automation with ε Moves ° A Non-deterministic finite automaton with ε - moves is a finite state machine in which states may or may not have a transition for each symbol in the alphabet. Some times the states of an automaton can have multiple transitions for a symbol. Additionally, it has transitions for empty input ε .

Acharjya 4 Analytical Definition ° Analytically, a non-deterministic finite automaton (NFA) with ε -moves is a five tuple, (S, , δ , s 0 , A), consisting of - S: Finite non empty set of states - : Finite non empty set of inputs called the alphabet - δ : Transition function from (S × ( ∪ ε )) 2 S - s 0 :Starting state, s 0 S. - A: Set of final states or accepting states.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
