Your input is a list/sequence/vector/array of 5-255 positive integers, not necessarily unique. You may assume whatever input format is most suitable, and that each integer (as well as the quantity of integers) is chosen uniformly at random from the range 5-255. The goal is to output the same li...

It might have been closed since we define languages by their implementation, so the implementation by definition cannot be wrong.

similar @Pavel

@ASCII-only it's more common to have func add(x: Int, y: Int) -> Int

btw what should lambda syntax be

closure syntax is descided

but lambda is not

@Downgoat :| i thought it was ->

or should we not have lambda and only closure

@ASCII-only that is function type signature :/

e.g. let add: (Int, Int) -> Int = ??:Int + ??:Int

@Downgoat that's usually first, second, a, b or left, right

@Downgoat then =>?

@ASCII-only but do we even really need

@Potato44 I don't think so

Potato44

or not, I forgot about the elements of m that would have to map to the overlap.

n!(mCn) would be the number of partial functions that are defined on the least number of elements such that they are a surjection.

@ASCII-only { (x, y): x + y }

@Downgoat hmm. weird, but yeah then we don't need lambdas

although imo we should make lambdas and closures mean the same thing in this case

We could probably get away with an xorshift lel

I'm not sure what to do: I feel like there are lots of vague, unenforced rules in the Dollar Bill Auction. That said, many KotHs also have vague rules (like "no reflection"). That said, this one does allow reflection, and has vague rules as to what is not allowed.

For example, there was a bot that exploited a bug in the runner, and he disallowed it because it was "attacking the runner", which 1. there isn't a rule against, and 2. Is vague.

7:57 PM

That sounds like a valid reason for a VTC to me

@moonheart08 xorshift128+ is much better than glibc's rand. Except for the LSB, it's actually pretty good for non-crypto applications.

another example is that he says that you can sabotage other bots, but if a bot calls one of my methods, and my function "happens" to take enough time to force a timeout, my bot is at fault

@Dennis Yea, then that's what i'll probably use

It looks like it could be done in about 6 x86 instructions, even. :)

@Nit I kind of picked it up as more and more answers were posted in it, and I occasionally use it when I think of a great algorithm

I'm VTC this as it is unclear what sabotage is allowed and what is not.

just disallow reflection

reflection is easy to enforce (as all of the reflection stuff is in certain packages that you can disallow)

@Pavel Due to your prompting, I spent much of today implementing the ]help user command. In 17.0, ]help ⌺ will cross-platform open the browser on the appropriate page. For all symbols it goes directly to the right page, for all other arguments, it searches the help system. Thanks for your input!

Cool, thanks!

So would it work for things like ]help )off or ]help ⎕TSYNC?

@Pavel One min, let me try.

@moonheart08 That's the size of the state. They generate 64-bit integers.

@Adám You could also make it print the definition of a symbol if it isn't a builtin, So e.g. f←{⍺+⍵}⋄]help f would print {⍺+⍵}.

@Pavel ]help off leads to search results where )off and ⎕OFF are the first two entries. I'll make it so that )off searches off. ]help tsync doesn't find anything right now, however I asked the chief architect if I could have a cross-platform hook into the interpreter to identify the correct help page for all such things, and he gave me hope that I'll get that, in which case both )off and ⎕TSYNC would go directly to the appropriate page.

Why would you need that? Just enter f: Try it online!

8:45 PM

@Adám I tried and got [down-triangle]f

@Pavel That's because you have boxing off. ]box on

Ah, ok

@Pavel That'll also use the nice display forms for nested arrays and tacit functions.

@Pavel Good. APL is becoming part of who you are.

Should I change the name of Make (a+b)(c+d) == a*c + b*c + a*d + b*d?

Not sure how to score that, since whoever writes their bot later inherently has an upper hand.

Perhaps allow multiple entries and the winner is whoever remains undefeated after N days of inactivity or something similar?
