MISTAKE POINTED - Shakhawat H 2 years ago (edited) The start variable is no where in the production rules, expect the first production rule. Then why should we replace the start variable????? "From a source, I have seen that the start variable is replaced only when the start variable exist in other production rules." ___________________________________________________________________________________________________________ Vyshnavi Vyshu 1 year ago This is wrong mam...bcoz whn the start symbol ki appear on the right side..thn we have to add the new production...s1---->s ... And also..u made a mistake in the step 2..while u r removing the epsilon production A ..we have to substitute epilson where A is present..but u substituted in one place there is another A ..but u forget it.. explained - 3:45 In other place ( first line ) there is already 'a' not need to add again.

No 1 ever cares to read your big paragraph Be short and crisp and point to point

[@Saifiadnan-hv5ln]

yes, but answer is right .... she just copy the javapoint website notes

[@kowshik-gu7cw]

Bro , mam is copied from website that's ok, any teacher in the world should refer books and websites to teach the concepts, mam using standard method for the start symbol she eliminate that in unit production , there is no mistake or wrong in it. Then, you mentioned step 2 mistake, even 2nd standard student should tells the answer that redundant shall be removed or no need to write. ______________________________________________________________________________________________________ If you think you are genious by finding the mistake, there is no mistake here. Please do not comment like this, by seeing your use less comment ,some student may avoid this channel.

[@ranahamza8239]

you didnt explain in line S --> a | aA | B why we didnt put null in capital A of that line ?

[@RJSR_1234]

because it is already having a if we put means it will get like s->a/aA/B/a it is coming 2 times so it needs to put

[@SouravSaha17]

there is no need to define a new start symbol because in RHS there is no S.

[@ameenshoaib6833]

isn't it? i had the exact doubt.

[@strawberry-cheesecake]

I thought the same thing

[@manilavaswani154]

This is wrong ..we use new production S' or S1 when on right hand side there is S but in this ques there is no S in right hand side but still u create new production.

[@sm6214]

She does not know that

[@kishoresaravanakumar8127]

Yup

[@saadmanahmed860]

in neso academy . learnt that new start symbol is to be made if S occurs on some right side. but u said sth different.getting confused

[@sakshiagarwal9568]

right

Yes dont refer to this

[@meshackstephen2019]

Good day, Priya, thank you very much for taking out time to put these videos out, your series has helped me immensely. however, in an earlier video where you introduced CNF, you explained away a unit production without eliminating it, while in this video, you've shed more light. I do not know how the contradiction can be reconciled, I just thought to point it out. thank you very much once again.

What about the repetition in S and So. Aren't we going to remove that.?

[@bharathgowda7953]

wf is it?? nothing I understood

[@veerenveerenpinisetty9388]

when x-.> a then the production we may get is s->X/XA/AX/b which may be not a cnf

[@omanshsharma6796]

X -> a does not mean that a -> X

[@akhilpadmanaban3242]

I had a doubt that why we didnt do removal of useless production. If we does that directly it iwll go to s1-->a,b which is in CNF. We can actually remove useless symbols from there @Education 4u

[@simarsinghchugh8402]

same question dude

[@simarsinghchugh8402]

did you find the solution for it ?

[@akhilpadmanaban3242]

@@simarsinghchugh8402 Yes bro, its been long back. We can do that too . Better follow remal of unit, epsilon and useless and then do further

[@cricaddict3638]

B is not reachable from start so why you didn't remove it?

[@binishabhattarai8895]

How A is reachable and from there we get B

Miss, why we took the new start symbol? is it mandatory? S1-> S

[@PetBuddies]

please let me know soon, Thank you

[@snehi_05]

If there is s on right hand side.. We have to take s'->s.this is the rule. here there is no need to take s'->s, because there is no s on rhs. May be she is wrong

[@siddharthdwivedi7745]

@@snehi_05 yes. It's wrong

[@wanderwithloka]

She Is Doing It As Per Rule But I don't think that matters... Apply it when there will be S In RHS.. Both Will Be The correct

Mam why u changed s1 to s0 mam
