Understanding NFA to DFA Conversion

What does NFA stand for?

• Non-deterministic Finite Automaton

• Non-deterministic Finite Array

• Non-deterministic Finite Algorithm

• Non-finite Automaton

What does DFA stand for?

• Deterministic Finite Array

• Dynamic Finite Automaton

• Deterministic Finite Algorithm

• Deterministic Finite Automaton

What is the main difference between NFA and DFA?

• NFA and DFA are identical in their state transitions for any given input.

• NFA allows multiple next states for a given input and state, while DFA has exactly one next state.

• DFA allows multiple next states for a given input and state, while NFA has exactly one next state.

• NFA has exactly one next state for a given input and state, while DFA allows multiple next states.

Can an NFA have ε (epsilon) transitions?

• No, an NFA cannot have ε transitions.

• ε transitions are only allowed in regular expressions.

• Only DFAs can have ε transitions.

• Yes, an NFA can have ε (epsilon) transitions.

Is it possible for a DFA to have multiple start states?

• A DFA can have one start state and multiple initial states.

• A DFA can have a start state that changes during execution.

• No, a DFA cannot have multiple start states.

• Yes, a DFA can have multiple start states.

What is the process of converting an NFA to a DFA called?

• Transition elimination

• Finite state reduction

• State minimization

• Subset construction

What is the state explosion problem in the context of NFA to DFA conversion?

• The state explosion problem occurs when converting a DFA to an NFA.

• The state explosion problem is a method to reduce states in a DFA.

• The state explosion problem refers to the increase in transition functions during conversion.

• The state explosion problem refers to the exponential increase in the number of states when converting an NFA to a DFA.

How does the subset construction method work in NFA to DFA conversion?

• The subset construction method eliminates NFA states to simplify the DFA.

• The subset construction method only works for deterministic finite automata.

• The subset construction method involves creating a single state that combines all NFA states.

• The subset construction method creates DFA states that represent sets of NFA states and determines transitions based on input symbols.

What is the significance of the transition table in DFA?

• The transition table defines state transitions for input symbols in a DFA.

• The transition table lists all possible states in a DFA.

• The transition table determines the final state of a DFA without input.

• The transition table is used to calculate the length of input strings.

Can a DFA be converted back to an NFA?

• A DFA and NFA are fundamentally the same and interchangeable.

• Yes, a DFA can be converted back to an NFA.

• No, a DFA cannot be converted back to an NFA.

• A DFA can only be converted to a regular expression.
