Woovin Youn
04:16
10% from the email I think
Justin Wang
05:44
saw amir using a {0,1}* notation yesterday. Is this notation allowed in the current definition of regex's?
Najmeh Arani
17:06
is k zero here?
Justin Wang
19:04
yes
Justin Wang
19:28
so the only states u can use are i and j, when theyre different u only include any transitions between i and j, if they are equal, u include epsilon
Najmeh Arani
20:22
thnx
Justin Wang
28:48
you need more than 2 states
Justin Wang
28:53
to have an intermediate
Justin Wang
32:33
ah nvm
Marco Baez
33:41
the star means repeated right?
Matthew Hunt
35:25
sorry where did that Rij^(1) equation come from again
Matthew Hunt
36:10
ohh ok
Aaron Geesink - agees001
37:54
so we need to make new regex expression until we get a superscript for all states in A?
Patrick D Fenn
41:05
yes
Harris Shepard
41:06
yep
Diego Vega
41:07
yes
Erik Kanamori
41:07

I like the name a lot already
Najmeh Arani
46:01
How did you choose s?
Najmeh Arani
46:54
It reminds me of a method we learnt in CS 120A
Justin Wang
47:16
group elimination?
Bilal Shafi
01:01:12
Plus means or
Boning Li
01:01:43
Oh tyty
Justin Wang
01:02:19
that is contrasted with concatenation (x)(y) which means writing one expression (x) first followed by a second expression (y)
Thomas Henningson
01:09:25
can we simplify after we use the formula?
Justin Wang
01:09:26
looks about right DX
Najmeh Arani
01:11:36
Would ask us to use the first algorithm to find a regex?
Najmeh Arani
01:12:08
yay!
Marco Baez
01:12:09
can you explain again how you got the loops for q0 and 2?
Marco Baez
01:12:54
