equivalent in power to DFA.
Conversion Techniques: NFA to DFA conversions are commonly used, with subset
constructions providing a formal method.
Formal Languages and Grammars
Formal languages are sets of strings over an alphabet, characterized by grammars.
Regular Languages: Recognized by finite automata; generated by regular
grammars.
Context-Free Languages: Recognized by pushdown automata; generated by
context-free grammars.
Context-Sensitive and Recursively Enumerable Languages: More complex
classes involving linear bounded automata and Turing machines.
Computational Models
Various models define what can be computed.
Turing Machines: The most powerful standard model, capable of simulating any
2
computable function.
