Hi there,
(first sorry for my question,it doesnt relate to this thread very much)
I know this kind of Regular Expressions,
I know e-NFA<----->NFA<------->DFA
then for every DFA we have a Regular Expression
for example we want to produce strings(with 0,1)that contains at least three adjacent 0's,
answer is: (1+0)*000(1+0)* (and then we can also draw its Automata)
now what are those regular expressions in above link?do those regular expressions
differ with these regular expressions I know?
(it seems I will see them in next sessions of my class?)

Hi Mehdi
