Finite Automata
What do you understand by the term Finite Automata ?
Expert
Finite automata is a simple model of computation
It reads input from left to right, and one symbol at a time
It maintains state: The information regarding what seen so far (“memory”)
Begin with deterministic finite automata (DFA)
It can be described by two ways that is, by diagram or formally.
State the Formal desrciption of DFA operation ?
Explain how light TP monitors allow distributed applications based on RPC to have transaction properties.
Explain DFA diagrams and DFA operation in brief ?
Give an algorithm that, given a grammar G = (V, Σ, R, S), decides whether the grammar G can derive the empty string.
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
What is the formal definition of DFA ?
Define various Terminologies used in TOC ?
Explain briefly NFA operation with example.
Let s1 and s2 be two strings of lengths m and n respectively. By definition, a superstring of s1 and s2 is one which contains s1 and s2 as substrings. Give a dynamic programming algorithm to compute a shortest superstring of t
Describe the theorem that a language L is recognized by a DFA if and only if L is illustrated by a regular expression.
