This is a very clear explanation; the theoretical part shed light on the practical example such that I could understand not only how to do it but also why it works. Thanks.

[@plinplinplonplinplonplin]

Can you explain why q0 and q2 are 3 equivalent with q1 not being a part of 2 equivalence?

[@spamspam5741]

Yes, q1 and q1 are in the same state (as you can see) and q2 and q2 as well, basically, there's no problem if both go to same state, as the state will always be contained in itself. It only causes problem, when it is going to 2 different states, and those states lie in different equivalence during previous stage

[@Digital_Sansaar]

That's great sir. I wasted an hour in understanding this topic through book and that doesn't help me. But your video is great within one example topic is crystal clear to me. Thnx

[@rawshn]

This video saved my life!

[@vaibhavsharma-gc4ce]

In the last step, i.e 4th equivalent, it is shown q0 & q2 paired but for q0 & q2 with 'a' going to q1, which is not in same group in 3rd equivalent. So how is it possible??

[@faizansiddiqui6862]

I also wanted to ask this

[@ThePositiev3x]

How can we talk about "3 equivalent states" while there are only 2 inputs? Also, q2 and q3 both go to q1 with input a. Shoudln't they be 1-equivalent?

[@bangvu2127]

Thanks for sharing the easier way to solve it. Professors at uni never tell us this

[@bikramthapa2687]

thank u so much sir for giving clear concept in all topics...

[@issacnadar302]

Sir by listening your lecture we understand the concept more thoroughly .thanks a lot.

[@pranavghadge7526]

why we cant directly draw the minimized DFA by seeing the same states from the table.

[@_KuchBhi_]

same Q bhai

[@gousiyashaik5665]

Of course bro observe it q4 is the final state so it's going to be separated q0 & q2 are have same states q3 is separated due to final state which is q4 Finally q1 is separated due to q3 That's it 🤠 it's very easy and simple bro U need to separate final States first and then separate every state by seeing it's states directly no need to write equivalents

Equal states go to same behaviour state or states q0,q1,q2 have same behaviour Y You separate q1

[@faizutty]

we got 2 equiv: as [q0,q2],[q1],[q3],[q4] at time 14.04... but in 3 equivallent we check for (q0,q2).. (q0,a)= q1 (q0,b )=q2 (q2,a)=q1 and (q2,b)=q2... then we can check in 2 equiv: table.. q1 is saparated... then how we can said that they are equivallent.. pls help me

[@malharjajoo7393]

+Faizal Basheer - Good point , I was wondering the same thing.

[@malharjajoo7393]

+Faizal Basheer - I think I get the logic. Think about this- if q0 goes to state q1 on symbol "a" , and q2 also goes to q1 on"a"... similar for symbol "b" .... then they are equivalent. This is in accordance to his explanation from before ....the problem you said , will only arise if while comparing two states , we go to two "different" states on a symbol. In this case , BOTH q0 and q2 are going to either q1 ( on "a" ) or q3 ( on "b").

[@faizutty]

+malhar jajoo haii... I got the logic later when I experienced with another examples..

[@faizutty]

if i dont remove tht state which is not reachable from initial State thn wht happens....? n can i solve my ques in exam without removing tht state....?

Thnk u dea dat ws really helpful

[@AlexFyra]

how are q0 and q1 equivalent if they go to the same state on a but to a different state on b? 8:45

[@shubham98309]

+Alex P. because both q1 and q0 belong to the same upper equivalent group that is they both belong to 0 equivalent group.

[@adityatanwar7301]

you did not read the definition right.it is because they are both going to a non final state. condition was either they must go to a final state or non final state

[@rahulsuryawanshi4396]

It was helpful Keep it up 👍👍👍👍

[@kamalhm-dev]

Man, why do you group q0, q1, and q2 in the same grouping?

[@davogrady]

but q3 is not an accepting state and he grouped it together with q4.

[@rathandevaki1491]

[@shiwanshukumar4186]

Sir , at 14:28 qo and q2 are going to q1 and q2 (on a and b ) respectively , whereas q1 is in different group. Hence we cannot put qo and q2 in same group . Kindly explain, if I am wrong .

[@naveenkumar-fn8nh]

at 14:28 qo and q2 are going to q1 and q2 (on a and b ) respectively but q1 and q0 are in the same group in 1 equivalent so u should not separate it. because when u r writing a new equivalent u need to check with the previous equivalent, if they belongs to same group in the previous equivalent u should not separate otherwise u can separate.

[@niharikachaturvedi6218]

naveen kumar But for 3 equivalent state we only need to check previous 2 equivalent state, right?

[@RAJEEV_NITIAN_007]

refer to 2:04 when sir said if (p,q) on seeing any i/p goes to same non final state then they are equivalent.So in this problem (q0,q2) goes to same state (q1,q2) on seeing i/p a,b so they are equivalent.

[@umarkhan-wh2zq]

but they are going to q1 which is not in the first brackets

[@chitrakarsanket]

Thank you sir!! can you please suggest me the best book for referring TOC ?

+sanket kurude K L P Mishra ( theory of computer science )

[@user-iv6gu3ls5b]

Really helpful!

[@sagaralwani75]

Thank u sir it's really helpful In last step seeing 2 equivalent we can say that q1 is in another set How q0 q1 are taken in same group pls help (I'm talking about 3 eqivalent)

[@igautammunot8714]

As u can see that q0 and q2 upon scanning with a and b reaches to same state as q1 and q2 respectively so they will always be equivalent, don't consider previous equivalent (in this eg. equivalent 2) in such cases

[@rustamahmed7519]

Why not we directly combine two equal transitions? like like rows 1 and 3.

[@5d8vamshiyaradeshi58]

Thank you so much

[@khanhakeem2590]

sir, agar given table me final state na ho to us ko kis tarah minimize krte hai

[@TheSunAgain756]

A DFA without a final state is known as a transducer. Mealy and Moore's machines are the example of FSM transducers. Since they produce an output corresponding to each state, it doesn't make sense to reduce their states.

[@hjolany1983]

[@singhRajshree]

How did u decide that q0 and q2 after combinig are start state???

[@IhsaanMuhiyadheen]

Because q0 is the initial state in the question. Just like q4 is the final state in both the diagrams, q0 is the initial state.
