Memaksimalkan output dari input minimal

16

Jelas, golf kode adalah tentang memanfaatkan kode paling sedikit. Siapa yang benar-benar peduli dengan hasil aktualnya?

Meskipun kami memiliki tantangan untuk rasio input-to-output tertinggi , ini adalah panggilan untuk output yang paling terbatas dan deterministik dengan panjang kode yang diberikan. Ironisnya, tantangan ini bukanlah .

Aturan:

  1. Tulis tiga cuplikan independen (bukan program / fungsi lengkap).

  2. Cuplikan harus dalam bahasa yang sama.

  3. Skor adalah jumlah total byte yang dihasilkan.

  4. Output mungkin dalam bentuk hasil, STDOUT, dll.

  5. Cuplikan mungkin tidak menyebabkan kesalahan apa pun.

  6. Cuplikan dapat menyebabkan berbagai bentuk output.

  7. Mengejar karakter baris baru tidak dihitung.

  8. Cuplikan pertama harus 1 byte atau panjang minimum yang menghasilkan setidaknya 1 byte output.

  9. Cuplikan kedua harus lebih panjang satu byte dari itu.

  10. Cuplikan ketiga harus dua byte lebih panjang dari yang pertama.

Ya saya pikir output perlu dibatasi secara teoritis terbatas, Anda juga mungkin harus menentukan bahwa itu harus deterministik (kecuali saya salah paham dan keacakan adalah sesuatu yang Anda benar-benar inginkan ...)
FryAmTheEggman
Apakah kami boleh berasumsi bahwa setiap cuplikan dijalankan pada instance REPL yang baru?
SuperJedi224
@ SuperJedi224 Ya.
Adám
Apa itu "bentuk" dalam "berbagai bentuk keluaran"?
Luis Mendo
@LuisMendo Misalnya, satu cuplikan mungkin memunculkan kotak pesan, sedangkan yang lain mencetak ke STDOUT.

Hexagony , 1 + 3 + 6 = 10 byte output

Ya ... bukan skor yang sangat mengesankan, tapi setidaknya saya bisa mengatakan itu optimal. Dengan satu byte, tidak mungkin untuk mencetak sesuatu dan mengakhiri, jadi kita mulai dengan dua byte:

!@

Kode yang tidak dilipat adalah

 ! @
. . .
 . .

Ini mencetak byte dan berakhir.

Untuk tiga byte kode, kita dapat mencetak tiga byte output. Contohnya:

o!@

atau dibuka:

@ . .
 . .

Terakhir, untuk empat byte, ada 169 cara untuk mencetak 6 byte. Karena tidak satupun dari mereka melakukan sesuatu yang lebih menarik (kecuali untuk aliran kontrol ganjil) selain solusi langsung, saya akan menyajikan bahwa:

o!!@

Dibuka:

 o !

Anda menebaknya. Mencetak 111111.

Labyrinth, 1 + 2 + 4 = 7 bytes

Another low score, which I'm mainly posting because I've proven it to be optimal for the language.

Like Hexagony, Labyrinth can't print and terminate with a single byte, so we start with two bytes:

!@

Prints a zero and terminates.

For three bytes, we can't beat the naive solution:

!!@

This prints two bytes before terminating. There are a few other options, like printing -1 with (!@ or ~!@ or ,!@. There is one pretty cool solution though which uses source code rotation:

!>@

This prints a zero, then shifts the source to become @!>. At that point it hits a dead end, turns around, and executes the ! again on the way back, before terminating.

For four bytes, it's a bit more fun, because the only way to print 4 characters is to use the above trick:

!!>@

Print two zeroes, shift to @!!>, print another two zeroes.

In all of these cases I'm ignoring that you can also print a byte with \ or ., because those will always print exactly one byte, whereas ! will print at least one and potentially several.

You can get an infinite amount of output bytes if you use the -F flag in Japt. What it does is that if the last expression of the program evaluates to false, it outputs the value specified in the flag instead. So I guess the score for Japt-F"Insert Super Long String Here" is infinity.

@CalculatorFeline I'm not familiar with Node.js, but on my Mac if you type in js on the command line, you get a JavaScript shell.

SmileBASIC 4, 1 + 13 + 15 = 29 bytes

This is going to be similar to 12Me21's SmileBASIC 3 answer, with a couple adjustments.

1

As before, the shortest amount of code to produce some output is 2 bytes: ? (PRINT) and some single-byte expression. The consensus is that PRINT does not produce a newline when it advances to the next line, due to the way the text screen works. So this results in one byte of output.

?1
1

2

With 3 bytes, we can do something different. SB4 introduces INSPECT, aliased as ??, which prints info about a single value. If we give it an empty string, for example, this can produce much more output than SB3 could. This gets us 13 bytes.

??"
STRING: (0)""

3

We have 4 bytes to work with, so we have to decide what we should do to maximize our output. Going with ?? is a safe bet; we only have 2 bytes to use on our expression, but the additional output of INSPECT is basically free. So I use it to print a label string. This is 15 bytes.

??@A
STRING: (2)"@A"

The total is 29 bytes.

Microscript II, 23+47+71=141 bytes

1: C

The stringification of continuations is not strictly defined by the specs, but in the reference implementation this, run on its own, yields a 23 byte string.

<Continuation @t=\d\d\dus> (\d represents a digit, which digits varies).

On my computer, at least, this does, in fact, always take between about 180 and about 400 microseconds to run.

The first use I've ever actually had for this instruction.

2: CP

47 bytes of output- the output from the first one twice with a newline in between.

3: CPP

Fairly straightforward. 71 bytes of output- the output from the first one three times with newlines in between.

Is this deterministic? If I understand you right, it contains varying digits...

@NBZ It does not produce the exact same strings every time, but it has produced strings of the same length every time I've tested it so far.

"output could change" - that's an understatement. In praxis, it would be impossible to reset the machine to the same state. Maybe a more deterministic alternative to the third?
Adám

Impracticality does not preclude determinism ... Unless you're meaning a different definition of "deterministic," in which case you should explicitly state so in the challenge.
AdmBorkBork
According to you, almost every program is deterministic, given the exact same machine state. The only exception would be equipment with true RNGs, e.g. based on microphone noise or camera input.

@NBZ True. I would certainly hope that almost every program is deterministic. Are you intending "immutable" perhaps?

Javascript, 312 + 318 + 624 = 1254 bytes of output

$
$$
$+$

The two functions $ and $$ are available in all major browsers' consoles, as shortcuts for document.querySelector and document.querySelectorAll respectively. Different browsers have native code coerced to strings somewhat differently from each other, and IE uses plain JS in each function resulting in much longer representation.

For the byte count, I'm taking the length of the string representation of each rather than the sometimes-modified console display, so the total bytes are, for each of the following browsers:

  • Chrome: 56 + 57 + 112 = 225 bytes
  • IE: 312 + 318 + 624 = 1254
  • Firefox: 33 + 33 + 66 = 132

(I'm considering the IE result to be the "official" count because it's the longest.)

For non-console browser environments, the largest outputs come from the following:

1
!1 // Or '{}' if being fed to a function instead of beginning a statement
Map

Results length by browser:

  • Chrome: 1 + 5 (or 15 if {} is usable) + 32 = 38 (or 48) bytes
  • IE: 1 + 5 (or 15 if {} is usable) + 38 = 44 (or 54)
  • Firefox: 1 + 5 (or 15 if {} is usable) + 36 = 42 (or 52)

These two sets of input produce the largest output possible in all of these browsers and consoles. To prove this, let's check all alternatives:

  • Existing variables: We can find all native available variables with maximum three characters with Object.getOwnPropertyNames(window).filter(x=>x.length<=3), and then map them to their string outputs to determine the larger ones. (Note that in some browsers such as Firefox, certain special console variables cannot be accessed this way as they're not a property of the window.)
  • JS has a limited number of types of literals that can be created with so few characters:
    • Per the spec, decimal numbers must be a decimal digit (1234567890) optionally followed by . and more decimal digits and/or an exponent part, or be a . followed by one or more decimal digits and optionally an exponent part. Other kinds of numbers must be either 0o, 0x, or 0b (or uppercase forms), followed by one or more digits. For our purposes, we can deduce the following:
      • There are only ten single-character numbers, which are the integers 0 through 9. The only two-character numbers are integers 0-99 (0-9 by adding a decimal after), and the numbers 0.1 through 0.9 by omitting the initial zero. The only three-character numbers are 0-999, including 0x0-0xf, 0o0-0o7, 0b0, and 0b1, the exponential 1e1 through 9e9 (10 characters), and the numbers 0.1-9.9 and .01 through .99. While not technically a number literal, NaN can also be referenced in three characters.
    • Strings, arrays, and regexps, each of which can take at max only a single character of content. An array could be filled with $, a comma, or a single-digit number. Arrays with only one element are coerced to strings as the element itself. Empty arrays become empty strings.
    • Depending on environment, it may or may not be possible to create simple objects with three characters. Normally, {} alone at the beginning of a script would be treated as an enclosure rather than creating an object. eval({}) returns undefined, eval({$}) returns the $ function. There are insufficient characters to surround the {} in ().
  • There are no keywords that are short enough to use. The keywords if, in, do, new, for, try, var, and let would all require a minimum of two other characters to use, exceeding the limit.
  • Available unary operators include ~, +, -, !, ++, and --. The two-character operators can only be used with a single character variable, of which there is only one ($), which yields NaN. The other four operators can be used with any one- or two- character value, of which there are:
    • Several variables. (On some consoles $, $_, $0, $1, $2, $3, $4, $, $$, $x ). When used with these operators, the results are limited to -1, true, false, and NaN.
    • 109 numbers. Results: Integers -100 through 99, -0.9 through -0.1, true, false.
    • Empty strings. Results: -1, 0 (-0 becomes 0 on toString), true.
    • The results of any of the one-character values above associated with a one-character unary operator. New results: None.
  • Usable binary operators (which must be a single character to have room left for both operands) are +, -, *, /, %, <, >, &, |, ^. They can only be used with a single-character value on each side. Options for values include $ and integers 0-9. Results of all combinations of these include Infinity, some numbers and binary values mentioned above, and numerous fractions which are coerced to strings of 19 characters or less (1/7 is 19 characters, unlike 1/9 suggested above which is only 18), and the text representation of $ preceded or followed by a single-digit integer or itself.
  • Finally, all remaining operators and expressions: The member operator . requires an existing variable and a identifier referring to a property. All uses of this here result in undefined. Surrounding a value in ( ) returns the value, as does assigning it with =. Using () or `` to call a value as a function results in undefined or errors with all available values.

Adding all this up, there are a grand total of 1651 possible outputs when using a Chrome console. The longest outputs for one, two, and three characters are from $, $$, and $+$ respectively.

None of which are particularly interesting, but dc isn't really great for spitting out piles of output. I do like that each answer builds on the previous. Anyway, F is just the number 15; f prints the entire stack; d duplicates top-of-stack; ^ raises next-to-top-of-stack to the power of top-of-stack (in this case, 15^15). I don't believe this can be topped in dc.

Ruby, 3+14+28 = 45 bytes

Why did I do this.

p

Prints nil.

$>

dup

Prints something along the lines of #<Object:0x0000000003610988>.

irb

Launches an instance of Interactive Ruby. Upon exiting, the returned object is #<IRB::Irb: @context=#<IRB::Context:0x0000000003643040>, @signal_status=:IN_EVAL, @scanner=#<RubyLex:0x00000000038900a0>> for 121, but since it requires you to press ^D or something to actually exit the irb instance, I wasn't sure if it'd actually count as a solution in "3 bytes" so I'm not actually including it in the score unless it gets an OK.

Runic Enchantments, 4,000,000 bytes of output

The first program is:

a@

Takes 2 bytes to: push a value to the stack, print a value from the stack, and terminate. In this case it prints 10 (though any integer value from 0 to 16 are also just as valid)

For 3 bytes:

aY@

Prints 10000, Again, a could be 1 through 16 inclusive (in order to generate more output than the original program, 0 is potentially valid under other operators) and there aren't a whole lot of operators that take a single input and produce any output, much less longer output. XCYZ:E are the only real options. aY@ is just the one that results in the most output.

P$!;

According to language specification, this runs infinitely. However as the interpreter has a built in "ok, that's enough" maximum execution limit, this is the most output achievable in 4 characters (and TIO cuts off execution after ~130,000 bytes for exceeding 128kib) and as the interpreter defines the language, this works. And while I have raised that threshold once before (from 10k steps to 1 million), I don't plan on messing with it any time soon.

Bigger?

If I invoke the three assumptions I made here, then sure.

`AA@

Which works out to Ack(65,Ack(65,64)), which aren't terribly large values to go shoving into the Ackerman function initially--certainly smaller than the 255 in the older post--but its ok, we can call Ack twice in 4 instructions.

And only god knows what it'll print.

Note: the A instruction has since then been made the Math meta-instruction, which consumes 3 objects on the stack: a char for what instruction to perform and then two inputs, x and y. As such this program doesn't actually do anything, both because neither A nor @ map to a math function and because two subsequent calls results in a stack underflow.
