TAILIEUCHUNG - Lecture note Theory of automata - Lecture 31

The main contents of this chapter include all of the following: Context Free Grammar, Terminals, nonterminals, productions, CFG, context Free language, examples. | Lecture note Theory of automata - Lecture 31 Lecture 7 Theory Of Automata By Dr. MM Alam Lecture 6 Recap JFLAP Introduction Practical Demonstration of JFLAP DFA definition Recap An FA is defined as follows - Finite no of states in which one state must be initial state and more than one or may be none can be the final states. Sigma Σ provides the input letters from which input strings can be formed. FA Distinguishing Rule For each state there must be an out going transition for each input letter in Sigma Σ. Construct a regular expression and correspondingly an FA for all strings that end in a double letter. The regular expression is as follows - a b aa bb a a 1- 1 2 b a a b b b a 4 b 3 Beginning and ending in different letters a a b b b a b a FA Optionality Behavior Can and Cannot represent Even-Even Language Dead or Trap States Dead states are used to implement the FA Distinguishing Rule. How to use JFLAP to draw dead states JFLAP Tour Again Even-Even Language in JFLAP Multiple Input Examples running using JFLAP Lecture 7 Summary FA definition RECAP How to build an FA from scratch What are Dead or Trap states in FA Trap or dead state Example using JFLAP
