## What is the non-deterministic state machine?

Definition: A finite state machine whose transition function maps inputs symbols and states to a (possibly empty) set of next states. The transition function also may map the null symbol (no input symbol needed) and states to next states.

**How can you say that a state machine is non determinism?**

In NDFA, for a particular input symbol, the machine can move to any combination of the states in the machine. In other words, the exact state to which the machine moves cannot be determined. Hence, it is called Non-deterministic Automaton.

**Are finite state machines deterministic?**

An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. Finite-state machines are of two types—deterministic finite-state machines and non-deterministic finite-state machines.

### How is non-deterministic finite automata implemented?

NFA stands for non-deterministic finite automata. It is easy to construct an NFA than 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. Every NFA is not DFA, but each NFA can be translated into DFA.

**Which is the example of finite state systems?**

There are many more examples of finite state machines we could use: a vending machine. a subway entrance turnstile. a heating system.

**What is the definition of a non deterministic finite state machine?**

Definition 1. A non-deterministic finite state machine (NFSM) is a 5-tuple , where , , and are the nonempty finite sets of states, input symbols, and output symbols, respectively; is the initial state; and is the transition function, where is the power set of .

## Which is the best description of a non deterministic automaton?

Non-deterministic Finite Automaton. In other words, the exact state to which the machine moves cannot be determined. Hence, it is called Non-deterministic Automaton. As it has finite number of states, the machine is called Non-deterministic Finite Machine or Non-deterministic Finite Automaton.

**When is the FA a non deterministic finite automata?**

If, for each pair of states and possible input chars, there is a unique next state (as specificed by the transitions), then the FA is deterministic (DFA). Otherwise, the FA is non deterministic finite automata (NDFA). What does it mean for an FA to have more than one transition from a given state on the same input symbol?

**Which is an example of a non deterministic choice?**

Start with an NFA (K,Σ,Δ,s,F) . We first do the construction and some illustrative examples and then deal with the proof. The basic idea is that the non-deterministic choice of states which can be reached by the string w is captured as a set of these possible states.
