Brainf*** Golfer

Question

One of easiest code written by a programming language is a program printing sequence of characters (ex. "Hello, world!"). However, some esoteric programming languages like Brainfuck, even this simplest code is quite annoying to write.

Your task is to write a program (don't have to written in brainfuck), which prints a (minimum-length) Brainfuck program printing the given text.

Input

A sequence of characters (between 1 and 255) is given by any format (variable, argument, stdin, file, ...).

Output

Output is a valid (no non-matching [ and ]) brainfuck code (assume unsigned 8-bit wrapping cell and unlimited number of cells to left and right) printing exact string that was given as input.

For example, one possible output for input A is ++++++++[<++++++++>-]<+..

Your program shouldn't take long time (>2m) to run.

The BF program shouldn't take long time (>10s) to run.

Scoring

(Notice : current scoring method may change, since it is not easy to calculate...)

The length of program (generating BF code) itself doesn't matter. However, hard-coding BF codes in the program code is not OK. Only acceptable range (ex. a BF code printing a single character 0x01 : +.) of BF codes might be hard-coded.

The score is sum of length of BF codes printing these strings.

• A string Hello, world! appended with a single 0x0A (\n) (i.e. the "Hello, world!" program)
• Single character from 0x01 ~ 0xFF
  • Sum of length of these 255 BF codes are multiplied by 1/16, rounded, and added to the score.
• List of first 16 strings, generated by splitting a random sequence of bytes generated on 11-11-11 by 0x00, removing all zero-length strings.
• Lenna.png, removing all 0x00s.
• Lyrics of the song 99 bottles of beer, starting with 99 bottles~, newlines are 0x0A, paragraphs are separated by two 0x0As, and no newline character at the end.
• Other strings you may provide.

Your program may include calculating the score of itself.

Of-course, lowest-score code will be the winner.

Answer 1

In Java, computes a short BF snippet which can convert any number to any other number. Each output byte is generated by either transforming the last output byte or a fresh 0 on the tape.

The snippets are generated in three ways. First by simple repetitions of + and - (e.g. ++++ converts 7 to 11), by combining known snippets (e.g. if A converts 5 to 50 and B converts 50 to 37, then AB converts 5 to 37) and simple multiplications (e.g. [--->+++++<] multiplies the current number by 5/3). The simple multiplications take advantage of wraparound to generate unusual results (e.g. --[------->++<]> generates 36 from 0, where the loop executes 146 times, with a total of 4 descending and 1 ascending wraparounds).

I'm too lazy to compute my score, but it uses about 12.3 BF operations per byte on Lenna.png.

    static String[][] G = new String[256][256];

                if (delta > 128) delta -= 256;
                if (delta < -128) delta += 256;

                if (delta >= 0) {

Answer 2

Well here's about the worst possible solution, although a rather nice looking one in Brainfuck itself:

++++++[>+++++++>+++++++++++++++>+++++++<<<-]>++++>+>+>,[[<.>-]<<<.>.>++.--<++.-->>,]

Score is probably the worst we are likely to see without intentionally making it bad.

Working on calculating actual score.

Answer 3

Score: 4787486 4143940 4086426 (without randomly generated data)

(4085639 of that are from Lenna.png. That's 99.98%)

I don't get the part with the random data. Don't I need an account which I have to pay for to get the data?

Pretty naive. Here's the generated code for "1Aa" (49, 65, 97) with a little documentation:

                   // field 0 and 1 are loop counters.
                   // The fields 2, 3 and 4 are for "1", "A" and "a"
++++++++++[        // do 10 times
    >
    ++++++++++[    // do 10 times
        >          // "1" (49) is below 50 so we don't need to do anything here
        >+         // When the loops are done, this part will have increased the value of field 3 by 100 (10 * 10 * 1)
        >+         // same as above
        <<<-       // decrease inner loop counter
    ]
    >+++++         // this will add 50 (10 * 5) to field 2, for a total of 50
    >----          // subtract 40 from field 3, total of 60
    >              // Nothing done, value stays at 100
    <<<<-          // decrease outer loop counter
]
>>-.               // subtract 1 from field 2, total now: 49, the value for "1"
>+++++.            // add 5 to field 3, makes a total of 65, the value for "A"
>---.              // subtract 3 from field 4, total of 97, the value for "a"

The Java code is a bit ugly but it works. The generated instruction per input byte ratio is probably better the higher the average byte value is.

If you want to run it, you have to put Lenna.png in the same directory as the .class file. It prints the score to console and writes the generated BF code into a file called "output.txt".

There are probably more efficient solutions, and more elegant ones, but this follows my thought pattern somewhat linearly, so it was easiest.

Well, I'm not going to win any prizes for the shortest output code but maybe for the program to generate the code...

x=input();o=''
for i in x:
 a=ord(i)
 o+="+"*a+".[-]"
print(o)

Answer 6

I'm a pretty bad BF programmer, so this answer is probably pretty inefficient. I'm unsure of the score, but it should perform slightly better than the existing answer on your average text. Rather than zeroing the cell out after every character, this one will "adjust" to a new character with subtraction if the previous character given is larger.

>>++++++[-<+++++++>]<+>>+++++[-<+++++++++>]>+++++[-<+++++++++>]<+>>,[-<+>>>>>>+<<<<<]<[-<<<.>>>]<.>>+>,[[-<<+>>>+>>+<<<]>>>>[-<<+>>]<[->+<]<<[->-[>]<<]<[->->[-<<<<<<.>>>>>>]<<]>+[-<<->>>[-<<<<<<.>>>>>>]<]<<<[>]<<.>[-]>+>,]

(Note, this is code I wrote a long time ago, and have repurposed for this competition. I sincerely hope I've done the conversion correctly, but if it fails for any input let me know.)

A version showing the state of the tape throughout the code:

>>++++++[-<+++++++>]<+>             [0 '+' 0]
                                           ^
>+++++[-<+++++++++>]                [0 '+' '-' 0]
                                               ^
>+++++[-<+++++++++>]<+>             [0 '+' '-' '.' 0]
                                                   ^

Answer 7

><>

i:&v

>:?!v"+"o1-
"."~<.15o
+-

I wrote this in response to a question marked for a duplicate, and even though this isn't the greatest golf (for this specific question, at least) I figured it'd be kind of a waste if I didn't share it in all of its disgustingly gibberish-y glory. Really, I'm half-surprised it even works. I'll take any suggestions to golf it down since that was my main goal in its creation.

As a side note, in the second line the beginning three characters .21 could be replaced with v followed by two spaces if that makes it any easier to read. I don't like to see spaces in my ><> programs because that means there's wasted space (literally). It also is a remnant from one of many prototypes.

The way it functions is really simple, and quite frankly I'd have a difficult time thinking of a way to implement another algorithm. It prints however many "+"s need to be printed for the first character, and then prints more "+"s or "-"s as needed for each additional character, separating each section with periods. What I find cool about the program is that it modifies its own source code so that it prints "+" or "-" (it replaces the "+" on line 3 with the appropriate character after determining whether the current character is greater than or less than the previous one).

Output for Hello, World!:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++.+++++++++++++++++++++++++++++.+++++++..+++.-------------------------------------------------------------------.------------.+++++++++++++++++++++++++++++++++++++++++++++++++++++++.++++++++++++++++++++++++.+++.------.--------.-------------------------------------------------------------------.

I might score this the way it was intended to be scored, but I'm almost positive I'd lose and I don't entirely know how to read something like lenna.png in ><>.

If this answer interests you and you'd like an explanation, by all means ask, but for now I'll leave it without one just because of how twisty and turny it is.

EDIT 1: It's been a while but I was able to golf off 2 bytes with an almost complete overhaul of the way the program decides whether to print a plus or a minus. It's a somewhat disappointing return for a large overhaul but at least it works.

Answer 10

I built something in Java. Didn't calculate the score. Texts with 3 or less characters are encoded with a multiplication per letter e.g. "A" = ++++++++[>++++++++<-]>+.. Texts with more than 3 characters are encoded with a calculated list which is split into 3 areas. The first area is x times 49, then plus x times 7 and finally plus x. For example "A" is 1*49 + 2*7 + 2

public class BFbuilder {
    public static void main(String[] args) {
        String text = "### INSERT TEXT HERE ###";

        if (text.length()<=3){
            String result = "";
            for (char c:text.toCharArray()) {
                result += ">";
                if (c<12) {
                    for (int i=0;i<c;i++) {
                        result += "+";
                    }
                    result += ".>";
                } else {
                    int root = (int) Math.sqrt(c);
                    for (int i = 0; i<root;i++) {
                        result += "+";
                    }
                    result += "[>";
                    int quotient = c/root;

                    }
