Step 1: Choose Automata Type
Select the type of finite automaton you want to build. Each type has different capabilities and use cases.
DFA
Deterministic Finite Automaton - exactly one transition for each input symbol.
NFA
Non-deterministic Finite Automaton - multiple possible transitions for each input.
ε-NFA
NFA with ε-transitions - can move without consuming input symbols.
Key Differences
- DFA: Deterministic, simpler to implement, one state at a time
- NFA: Non-deterministic, multiple possible paths, set of current states
- ε-NFA: Most flexible, can make transitions without reading input
