does the code run so that it tests all entries in the matrix or just the first row?
#quants-n-traders

bingo
i guess intuitively it makes sense cause as your matrix gets bigger and bigger more and more paths are going to intersect until there is only one path?
dire finch
ya i think the fact that the entries are only up to [M - 1] forces paths to intersect eventually
spiral rivet
yeah that would make sense. would there be any way to model this in the context of a transition matrix though
for example a transition matrix of starting from col i in row 1 to col j in row 2
dire finch
hmm lemme think
low vault
I think I kind of get it now?
low vault
I htink you should've explained what "moving forward" meant
e.g. that
specifically
you were moving left->right, wrapping around to the next row when your'e done
dire finch
I think I kind of get it now?
markov transition, N * N states and M[i][j] for (j in [i + 1, i + N]) = 1 / (N - 1)
low vault
wait wat
spiral rivet
where the probabilities are all 1 / (N - 1)
don't rows of transition matrices have to sum to 1?
low vault
FYI this matrix is a really bad example
no matter where you start you end on column 1 I think
dire finch
no matter where you start you end on column 1 I think
no that's the conjecture
spiral rivet
I htink you should've explained what "moving forward" meant
sorry yeah definitely could have worded it better
dire finch
i think the better problem statement is
given a vector of size N * N with entries v_i \in [1, N - 1]
start at any entry [0, N - 1] and march forward sequentially by v[cur] steps
spiral rivet
no matter where you start you end on column 1 I think
for this 5x5 one no matter where you start you would end up on row 5 coloumn 5
dire finch
prove that there is only one absorbing state
low vault
prove that there is only one absorbing state
for all cases, or like on average?
it sounds like this is only true on average 👀
spiral rivet
yeah thats the idea of the problem
dire finch
for all cases, or like on average?
well probabilistically
low vault
ah
dire finch
so u model the thing as markov
low vault
so like lim(n->infty) P(multiple absorbing states) = 0?
dire finch
and have transitions i -> [i + 1, i + N] = \frac{1}{N - 1}
low vault
oh I was just thinking of like drawing trees lol
low vault
for this 5x5 one no matter where you start you would end up on row 5 coloumn 5
how do u end up on column 5 wat
dire finch
i think markov wise you wanna prove that the stationary state has max (1 - \epsilon)
low vault
maybe you can spam combo
low vault
and have transitions `i -> [i + 1, i + N] = \frac{1}{N - 1}`
yeah that seems ab rye
setting up
spiral rivet
start on 4 on row 1 col 2, the next steps are: 3, 3, 1, 4, 1, 2, 1, 1, 2, 1
low vault
i just dk like the lingo and theorems lolol
low vault
start on 4 on row 1 col 2, the next steps are: 3, 3, 1, 4, 1, 2, 1, 1, 2, 1
er
doesn't this end on the bottom left
spiral rivet
right but at row 5, col 1 you can still take one step to the three and then take three steps to the 5
low vault
there is no 5 in the matrix??? (I assume you mean the 1 on row 5 column 5)
dire finch
and have transitions `i -> [i + 1, i + N] = \frac{1}{N - 1}`
edge case: if i \in [N*N + 2, N*N] then it also has absorbing transition M[i][i] = (N*N - N + 1 - i) / (N - 1)
low vault
right but at row 5, col 1 you can still take one step to the three and then take...
okay wait, then when do you stop then?
when you reach the bottom right corner?
I'm confused because
dire finch
you stop when you can't march forward anymore
low vault
doesn't that just mean every process stops at the very end?
low vault
you stop when you can't march forward anymore
oh
dire finch
not necessarily
spiral rivet
okay wait, then when do you stop then?
you would stop when the number that you have reached is too big and would cause you to jump out
spiral rivet
I think what i'm looking for is a way to show that if you have transition matrix P, for some P^n, there is guaranteed a column of 1's
low vault
do you mean a row
of 1s
oh wait
nvm it's on teh transition not the original matrix
spiral rivet
yeah so basically for some n, all states go to a certain column with probability 1
low vault
i think intuitively
if you loko at the process row by row
it gets iteratively more skewed
but im too fried to make any serious formal argument xd
i think in my head it's just like
the probabilities pile up more to the rightmost columns in each row
nvm i think im too fried for this
and dont know enough markov chains
low vault
edge case: if `i \in [N*N + 2, N*N]` then it also has absorbing transition `M[i]...
wait hold on
I was just wondering
but it sounds like you can make a argument only on these states?
like as i goes from N*N - N + 1 to N*N the absorbing transition becomes higher and higher probability
ocean bloom
Any quant meet ups/networking events in nyc this summer ?
dire finch
after some light brain mashing i think probabilistic argument is not good
low vault
o nvm it deosn't actualyl decay on its own oops, gotta include the other states
low vault
waaaaaaaah
dire finch
waaaaaaaah
you need to augment the matrix with more absorbing states
cuz u shouldn't be able to move mass out of the last row infinitely many times
low vault
o.o
dire finch
otherwise it's trivial from transition analysis that u will always end up at N*N
which is stupid as fuck
spiral rivet
right so the matrix for the last row would be different
dire finch
you will have transition matrix of size (N(N + 1), (N*N+1)) where the bottom right diagonal matrix of size N * N is the identity
and then u can do fundamental matrix analysis
hooooly fuck im cooked
low vault
I think what i'm looking for is a way to show that if you have transition matrix...
this is a nit but I think you want to say that lim(n->infty) P^n contains a row with only 1s or whtaever
there shouldn't be a finite n with that property
dire finch
ok i finially understand the structure of this goofy ass problem
this is why im not qr orz
dire finch
P = [Q R; 0 I_{N - 1} ] \in R^{(N^2 + N + 1)^2}
Q = {\frac{1}{N-1} if j \in [i + 1, i + N - 1]; 0 otherwise}
spiral rivet
`P = [Q R; 0 I_{N - 1} ] \in R^{(N^2 + N + 1)^2}`
this would be the transition matrix?
dire finch
R \in R^{(N*N) * (N - 1)}; the bottommost (N-1)*(N - 1) chunk in R has the form diag(\frac{1}{N-1} ... 1)
im cooking with gas
spiral rivet
keep cooking please im taking notes
low vault
QR speedrun
dire finch
ok and then u do B = (I - Q)^{-1}R
B[i][j] is "chance of landing in absorption j starting from i"
spiral rivet
no, this is just the game but we are trying to model with a transition matrix
dire finch
we want to show that there is some invariance with the "starting from i", i.e. that the absorption probabilities are equal no matter where you start for i in [1, N]"
spiral rivet
i think the better problem statement is
and this is best version of problem statement
dire finch
we would like to show that the paths converge
probabilistically that means the absorption probability distribution for each initial state is the same
i think?
someone smarter than me prob alr knows im wrong
im orzed..
spiral rivet
probabilistically that means the absorption probability distribution for each in...
lol what classes did you take that taught you how to even come up with this matrix
so no matter where you start on row 1, you always end up on the same column in the last row
dire finch
no matter where u start in the first row ur markov transition looks the same; in a seeded run it means that ur union find for all of ur paths have the same parent (almost always)
dire finch
lol what classes did you take that taught you how to even come up with this matr...
this is like basic stochastic process and probability class
from [1, N - 1]
i think this statement is generically true for any iid distribution from [1... 1 + K < N]
might even work with a gaussian thing
or some arbitrary distribution
this is probably a percolation problem in disguise where the percolation threshold is inversely proportional to the leap size [1, 1 + K}
since we pick K = N - 2 this must be much lower than the percolation threshold

the fact u can tag andrew at 5 am

no GLAZE but my goat andrussy rly is about what he preaches

i think it's easy to vibe out that, after one run to a terminal index T (call this path P_T for some T), the number of tiles that you could hit on a subsequent run that is not part of P_T is monotonic decreasing (keep merging into P_T etc).
maybe it's a pigeonhole thing where you have N initial starting points but [N - 1] transition targets

is it actually? wait holy orz why do i pass cit rez
tbh it was citsecnot cit and apparently citsec screen nicer
oh really? i’ve heard citsec is more school agnostic and will pass more people than citadel will
my hope is to pass citadel screen for gfi later
i think swe diff bc the process runs simultaneously but like
for non swe the process is seperate i think
and then team matching to MM teams is probably more difficult than team matching to a more traditional infra team in cit like equities or sum
yeah def

When applying to undergraduate programs like Discover Citadel, LaunchPad, and Discovery Day, would it look bad if I list an internship at a different firm for the following summer? I'm wondering if including that experience might make me seem less committed or less appealing to them if it's with a competitor.
Ok great thanks!
Yea, I just want to go to the event lmao
When do they expect grad for winternships? The following spring?

oh i see
but it probably wouldn't be until later years right
or is T10 enough to get a qr internship freshman year
cracked in what sense
oh i see
usually quant companies don't care too much about projects right
cause the type of work they do probably isn't even possible without the resources they have
i mean cracked in terms of what
previous internships?
oh yeah for swe it makes sense
swe is completely different right
as in the role of swes and their expectations for them at quant firms is completely different than for other roles right
like compared to qr/qt/qd
oh
nevermind then
i swear every company has their own vibe when it comes to role classifications
why can't there just be a unified role system 
cause previously i saw people here talking about qd and qr as if they're the same
what would swes at quant firms do
oh i see
so the role possibilities are pretty much as vast as for any other industry

How I feel applying to a trading role knowing damn well I’ve never taken a probability class before
storm igloo
Learning probability by classes ❌
Learning probability by failing interviews and taking notes ✅
tiny sleet
are the probability questions usually general probability problems
or are there also things that are specific to quant that you'd only see in a quant math class
tiny sleet
so a quant math class wouldn't help at all for interviews
probably would help a lot for the job itself though

so a quant math class wouldn't help at all for interviews

intro quant math class at my uni
there's two more lol
one of them is the continuation of this
and then the other one, i have no clue what it is, i think it might just be some basic number theory class with some slight quant specific content
untold prawn
^^
tiny sleet
i think that gets introduced in the second class
probably still gonna take both classes cause they're helpful
tiny sleet
which one
the first one says "particular emphasis on models for pricing derivative instruments such as options and futures"
the second one says "probabilistic techniques and concepts from the theory of continuous-time stochastic processes and their applications to modern methematical finance"
insane typo on their part 🙏
"methematical"
and this course has a hard prerequisite of grad level probability theory lol
i probably will
