Key Concepts
- Language acceptance
- Transition functions
- Equivalence of DFA and NFA
- Closure properties of regular languages
2. Formal Languages
Formal languages are sets of strings over an alphabet, and understanding them is crucial for designing and analyzing computational problems.
Language Classes
- Regular Languages: Recognized by finite automata
- Context-Free Languages: Recognized by pushdown automata
- Recursive and Recursively Enumerable Languages: Recognized by Turing machines
Operations on Languages
- Union, intersection, complement
- Concatenation and Kleene star
