I'm Brazilian. So so far from India. I watch many videos from Indians and I think they are excelent. I have a little difficult to understand the accent sometimes but I like very much. The contents are amazing. Anyway, there is no so many videos like that in Portuguese. Then, I need to look for content in English.
@@likeapple1929 most numbers of that set? what? no. listen: 2^Q is the powerset of Q.i studied mathematics. it has always been and always will be the powerset of Q.
An easy way to remember how epsilon functions that I use is to consider every possible string that goes into the machine to have 0 or more epsilons between each of its symbols. i.e. if the string is 'aba' I consider it to be 'ε*aε*bε*aε*'. I'm not sure if this is correct but it has worked for me for now. Please leave a comment if you disagree, I really want to know why.
So if Epsilon means a state goes back to itself by default, does that mean If this parameter is considered in case of DFA, we don't have unique next state, It has one unique next state and the epsilon by default?
Epsilon (also commonly referred to as lambda) is NOT a symbol. It doesn't mean empty symbol. It's a string, and it is the reason why the set of symbols for a language will never include epsilon (a.k.a. lambda).
lambda REQUIRES empty string to use the transition where epsilon functions as a 'free' move. When the machine encounters lambda, it cannot proceed without an empty string/symbol...when it encounters epsilon, the machine is allowed to move across the transition for free while creating another 'thread' of execution.
