A deterministic finite automaton is a 5-tuple
(Q, Σ, δ, q0, F)
- Q is a finite set called the states- Σ is a finite set called the alphabet- δ:Q x Σ→ Q is a function called the transition function - q0 is an element of Q called the start state- F is a subset of Q called the accept states
Describe the Strategy of TOC computation box in brief ?
Let REGEXP be the language of valid regular expressions over {a, b}. That is, REGEXP is the set of all strings over the symbols Σ= {a, b, (,), U,*, ^} that are valid regular expressions. For example, the string “a (a U b)" is in REGEXP, whereas the string
