Why this have an unclear VTC

Nathan Merrill

@TuxCopter bunch of reasons

it was a long debate about how to prevent certain answers from occuring

hey...does serial voting reversal actually change the vote?

or just reverse the rep change?

TuxCopter

AFAIK it reverse the rep and the votes

Mega Man

@TuxCopter There are incredibly many questions which are hard to identify and could be considered a standard loophole if we had loopholes for this type of questions. You could even write a new challenge and at least get 1 or 2 points...

Oh no, you can't., sorry.

Nathan Merrill

I did close that loophole

And that's what I didn't read XD

Nathan Merrill

I won't deny that there might be other loopholes, but I try to close them as fast as I get the report

Mega Man

But I still know a bunch of questions which maybe aren't even unique.

Of course, you can't find every question, but it's still a bit unfair sometimes

Article 50 of the Treaty on European Union

Article 50 of the Treaty on European Union is a part of European Union law that sets out the process by which member states may withdraw from the European Union. Its use became extensively debated after the referendum held in the United Kingdom on 23 June 2016 in which a majority of those voting favoured the United Kingdom's withdrawal from the European Union. Once article 50 is triggered, there is a two-year time limit to complete negotiations. If negotiations fail to reach agreement, the member state leaves with nothing. This process is generally accepted to leave a seceding member without any...

@TuxCopter The parlament has to agree to this and they didn't. Noone said they wouldn't, but they didn't

mınxomaτ

@MegaMan Nothing happened yet at all. The vote wasn't legally binding by any actual law. It's worth nothing more than a strawpoll at this point.

Mega Man

@mınxomaτ That's exactly what I meant :P

mınxomaτ

@MegaMan But not what you said. First of all, they are not out. Second of all, nothing about this is illegal.

illegal and not legally binding are two very different things

Mega Man

@mınxomaτ Yes, sorry, I did say it wrong. I didn't mean it's illegal. I meant - again - exactly what you said :P

@Lembik I made a distributed version of the program. In total I have 18 cores at home (though several are pretty slow). Working on n=14 gave this after a bit less than a day

I checked the solution with 2 different programs, so I'm quite sure it's valid

Erik the Golfer

@Flp.Tkc I think that it's not a dupe, since, first of all, you are required to show the user how the heck to type it, not how much they should count.

Flp.Tkc

ok. thanks for the feedback :)

PhiNotPi

when is group B test recording? I could do it then.

Ton Hospel

@Lembik: ps, for you your 50 column matrix, I can only confirm that at least the first 45 columns have no solution. I can probably get 1 more column, but then I will run out of disk space. (complexity is O(3^(n/2))

I would need about 32Tb of disk space for a full check

perhaps more importantly, do the results seem to make intuitive sense?

I suppose banning minor version differences might help un-dupe it

Flp.Tkc

@ETHproductions yolo

ETHproductions

3:42 PM

While I'm at it, should I just ban all versions of the same language, e.g. Python 2 and Python 3 is not allowed? I remember seeing a golfing language where the version number was something like 27.0.1

Or should I just not worry about that?

Nathan Merrill

I think its totally fine to alllow it

because they'd have to abuse version-specific behavior

Kritixi Lithos

I agree with @NathanMerrill

ETHproductions

OK, cool. Do you mean minor versions should be allowed, or just major versions?

Nathan Merrill

any version

a patch version, if they want

ETHproductions

Hmm... I'm afraid it'll be closed as a dupe of "What year was this language released?" then

Sp3000

3:47 PM

@Mego It's pretty nontrivial to use crypto to make an uncrackable submission, if that's what you mean. Most CnRs have this problem :/

Nathan Merrill

for languages like Python, its easy to define version level, but for many other languages (like most esolangs), its tough to say "this is major version" vs "this is a minor version"

@Sp3000 you mean trivial?

Sp3000

... yeah trivial, oops

Nathan Merrill

@ETHproductions actually, as I think about it, I'd prefer if multiple version of the same language weren't allowed

because, at least in python, its trivial to check the version number

ETHproductions

My thoughts exactly

But should Python 2/3 be allowed in the same entry? They're quite different

Nathan Merrill

that's a major version IMO.

yeah, there are differences, but not that many

PhiNotPi

3:52 PM

@LuisMendo most of the interesting stuff occurs under the "opCoin" package github.com/PhiNotPi/BernoulliFactory/tree/master/src/opCoin

I haven't really done much documentation yet, other than like a 1-line comment in each telling what the math expression is.

ETHproductions

@NathanMerrill I'm not sure I understand what you're saying... you're against it?

Nathan Merrill

yeah

PhiNotPi

For example, OverOnePlusTimes.java is the code for x/(1+xy) which is constructed by the code new Mult(x, new Neg(new Mult(y, this))).

Nathan Merrill

I'd either allow all version, and allow Python 2 and 3, or allow no versions

ETHproductions

I agree that there's no safe middle ground

All versions is too close to What Year? IMO, so I think I'll stick with no versions

PhiNotPi

3:55 PM

Which I find to be a very convenient way of organizing stuff, since existing functions can be composed however I like. The above example only requires a single line to compose several other functions into a recursive function for the desired result.

The downside is that the resulting algorithms aren't necessarily efficient.

Nathan Merrill

if you are composing algorithms like that, why are you putting each algorithm in its own class?

IMO, it'd be simpler to just create an Array/HashMap of them all

PhiNotPi

@NathanMerrill how would that work (for functions that aren't compositions)?

Nathan Merrill

well, you'd have two operator interfaces

(it depends on how many arguments the operator takes)

PhiNotPi

The way my OO works is that there's a superclass "Coin" which is anything that has the "next()" method to return 1 flip. Each coin-function takes several parameters (some of which are Coins), but is itself also a Coin.

The arguments for each operation are unique to that operation.

ETHproductions

> Each submission must run in at least 3 languages, each of which must output a different item from the menu. You may not use multiple versions of the same language (e.g. Python 2 and Python 3 cannot be used in the same answer).

@Nathan How does that look?

Nathan Merrill

4:06 PM

@PhiNotPi I'm not sure I understand the purpose of this package

@ETHproductions goood

PhiNotPi

@NathanMerrill as in, why it's a separate package?

Nathan Merrill

no, like...what is it even doing?

why are you taking multiple coin flips

PhiNotPi

Here's a simple example. You have two coins, X and Y, with probabilities 1/2 and 2/3 respectively.

Let's say that you wanted to combine these coins to create an X*Y coin, which lands on heads 1/2*2/3=1/3 of the time.

The answer is to flip both of them, and if both return heads, also return heads.

Nathan Merrill

why not just multiply the probabilities?

PhiNotPi

Because you don't have access to the probabilities.

Nathan Merrill

4:16 PM

what benefit does that provide?

PhiNotPi

Bernoulli factory algorithms don't take real numbers as input and return a real number as output, they take a sequence of heads or tails and return either heads or tails. The probability of the result is a known function of of the unknown probabilities of the inputs.

Probably the most practical application is the typical "create a fair coin from an unfair one."

One last question before I post: Should each entry A) have the same bytes in each language's encoding, B) have the same chars in each language, or C) be required to have the same encoding in each language?

I'd go for bytes

ETHproductions

How would I phrase that in the rules?

Kritixi Lithos

> Each entry have the same bytes in each language's encoding

ETHproductions

Thanks, that's simple enough. I was writing something like "Each entry must be runnable from the same file, i.e. ..." which didn't go well

Kritixi Lithos

I just restated your own words from a few minutes ago

Flp.Tkc

@ETHproductions add up the bytes in each language's encoding and divide by total languages?

ETHproductions

@KritixiLithos Oh, haha :P

@Flp.Tkc That sounds a little too complicated

Erik the Golfer

^ I agree, that sounds too complicated.

Flp.Tkc

sorry haha. was just giving a suggestion

Calvin's Hobbies

@PhiNotPi Is there a way to do that without potentially getting an infinite loop? (Like all heads)

I guess not. a 100/0 coin could not simulate 50/50
