The Post Correspondence Problem

[@emmanuelsherman3066]

You’re a true legend in TOC. I will tell all of my friends to follow your lectures. You make problems explicit and solvable better than those I am paying to teach me at college. Thank you so much.

THANK YOU! I learned more in your 14 minute lecture than a 1 hour lecture by my professor :D

[@DenisG631]

Thanks! It helped. So it's not decidable, but it is recognizable, right?

[@DarkOceanShark]

Yeah

[@rishiupadhyay3956]

If I had studied it a couple of weeks before, I could've scored 2 more Marks in NET. Anyway, "girna nahi gir k samhalna hain zindegi" Thank you for this nice presentation as well as explanation.

The numerators are the input to the transfer functions, denoms are the outputs. Being able to cancel everything out means you're at the end state (from end state -> end state ~ means nowhere else to go). The hashes mean you're at the end of the input string?

You literally guaranteed me 25% on my final. Thanks!

[@vishalkumargvkg2161]

Thank you sir ... finally I understood pcp

[@vishnumuralidhar5659]

In the example 2 we have to use only domino 2 because 10111 and 10 but when I choose domino 1 mean 1 and 111 then there is no other go for 11 takes place.

[@vedikaagarwal1859]

Is it necessary to use all the dominos while coming to final PCP solution?

[@godfather_007]

Sis you got answer for this ? Should we include all dominos to get ans ?

[@ankitakhokhar7833]

@@godfather_007 it's not necessary.

[@ramkumarbouthu4632]

How the question will be asked in this particular PCP problems and how to convert the question to above example ....tell me

[@rishiupadhyay3956]

UGC-NET DEC 2019 Let A={001,011,11,101} & B={01,111,111,010} similarly, Let C={00,001,1000} & D={0,11,011} Which of these pairs have a post-correspondence solution? The solution is: pair (A,B) only. Try to find the solution yourself.

[@yogeshrawat5095]

Very nice explanation sir !!

[@mayureshsulakhe9165]

Teach -> RICE's Theorem

[@chandrikakc1179]

[@aneesfatima9528]
