Hello

orlp

1:03 AM

@LeakyNun given some 2-1 gate g (e.g. NAND), n inputs and k outputs, how many distinct non-cyclic circuits can you form with j gates?

Leaky Nun

is this supposed to be easy? :P

Zacharý

Define "distinct". Distinct setup, or output?

orlp

where distinct refers to the output

with the only information about g is that if a = c and b = d then g(a, b) = g(c, d)

@LeakyNun no :)

Leaky Nun

do you have an answer for it?

orlp

no :)

Zacharý

1:05 AM

There's an easy way to find an upper bound, at least.

orlp

yes, that's easy

Leaky Nun

so it's a finite problem

orlp

yes

Zacharý

It's at most (2^2^n)^k, right?

ngn

@orlp only 2 then: 0 and 1?

1:07 AM

@ngn 0 and 1?

Blue

Random question: anyone know where I can get a temp email that I can send from?

orlp

an example of two seemingly distinct but actually equivalent circuits (in single assignment form):

t1 = g(i1, i2)       t1 = g(i3, i4)
t2 = g(i3, i4)       t2 = g(i1, i2)
t3 = g(t1, t2)       t3 = g(t2, t1)
o = t3               o = t3

or another example

t1 = g(i1, i2)       t1 = g(i1, i3)
o = i1               o = i1

user202729

@Zacharý eh...

gmail and yahoo want a phone number

user202729

@Blue Gmail doesn't.

Zacharý

@user202729 I think after a few emails they do

Blue

Pretty sure it did when I tried signing up

Ah

ngn

@orlp if you're asking how many outputs are possible - well, there's only two of them :) I'm sure I'm not interpreting the question correctly.

Blue

I'm using tor for it so that would do it

user202729

1:09 AM

@Zacharý I believe I have 5~6 ones. How much is a few?

orlp

@ngn well I never said anything about the type, I never said these were logic gates

Zacharý

:43550488w/ gmail?

orlp

@ngn to go beyond that, two circuits are equivalent if for EVERY POSSIBLE INPUT, they have the same output

user202729

@user202729 Zacharý is replying to this.

@Zacharý Yes.

Blue

@orlp ok, that makes sense

Blue

They want a phone number

user202729

@Blue Really...? let me try creating one.

moonheart08

Gmail requires a phone number now

orlp

@LeakyNun cs.stackexchange.com/questions/89575/…

a simple upper bound is as follows

the first gate 2 times the choice from the inputs, so n^2

the second gate has 2 times the choice from the inputs but also the output from the first gate, so (n+1)^2

so you get n^2 * (n+1)^2 * ... * (n+j)^2

Zacharý

Would that have been better on Math.SE ?

user202729

1:13 AM

@moonheart08 ... indeed.

orlp

finally each output can be any of the inputs or any of the gates' outputs, adding another (n+j)^k choices

but that doesn't do any distinct checking

@Zacharý don't think so

Zacharý

There's probably an OEIS sequence in all honesty, with fixed n or k.

orlp

I would probably try k = 1 first

Zacharý

When in doubt, fit it with a pol... never mind, this is multivariate.

user202729

... Just tried yahoo, gmail, microsoft, doesn't work.

orlp

1:27 AM

@user202729 google.nl/…

have you tried, you know, googling?

ngn

@orlp So, if we compute g(x) for some vector x that's a k-tuple of inputs, and add that g(x) to the original set of inputs, we have a problem of size j-1?

orlp

@ngn g is a binary function

if you have 3 inputs, a, b, c, then there's 9 possibilities: g(a, a), g(a, b), g(a, c), ...

suppose k = 1, so only 1 output

when n = 3 and j = 1, it's indeed only those 9 possibilities

and they're all unique

j = 2 and stuff already explodes

9 possibilities for the first gate, then (3+9)^2 = 144 possibilities for the second gate

ngn

@orlp Hm... ok. I'm a slow learner. So we're not interested in the values on each output "wire" but in the number of distinct "wirings", so to speak.

orlp

@ngn correct

ngn

@orlp ...and two wirings are considered equivalent if they compute the same function on the inputs?

orlp

1:37 AM

@ngn also correct

user202729

@orlp Wrong search term...

(often, I only can google questions I already know the answer)

orlp

@user202729 " Random question: anyone know where I can get a temp email that I can send from? "

@orlp oh ok, I was going to ask if you have estimates for n, k, j and the number of distinct values in the data type

Destructible Lemon

ok idea: language with 3 stringly typed registers, but the only way you can do any comparing of these registers, is checking if they've been activated (if you have the string "blah", you can activate it, and if you then have a string "bla", which you then add h to, you can check if it's activated, and conditionally do an operation)

or with numeric registers. or both

I think it might be interesting to prove the turing completeness of it

although, if you can delete characters, could it be easily reduced to a minsky machine?

quartata

i don't really get what you're describing but it's almost certainly a tag system

Destructible Lemon

I don't think it is

Zacharý

2:24 AM

you mean strongly?

Destructible Lemon

stringly typed is a pun

basically it means it uses strings rather than a more practical integer type

@quartata there's no chase, for one thing. the first characters probably don't get deleted

oh and also you can't unactivate strings, to make it more difficult

Zacharý
