Generate a mandelbrot fractal

51

Your task is to draw the mandelbrot set in ascii. It should look something like enter image description here

The complex number c lies in the mandelbrot set, when the sequence z(n+1) = z(n)^2 + c, z(0) = 0 remains bounded. For the purpose of this challenge you can consider the sequence bounded for c if |z(32)| < 2.

Plot the mandelbrot set on the complex plane from (-2 - i) to (1 + i), and a minimum resolution of 40x30, using ascii characters in your favourite language, using as few characters as possible.

@dmckee a good way to parameterize the Mandelbrot fractal is to change it to a Julia fractal :) It's the same algorithm z = z^2 + c except for Julia c is given as input and z0 is the point we are checking – aditsu quit because SE is EVIL – 2013-03-08T14:31:22.207

The complex number z lies in the Mandelbrot set if the sequence (u(n)) defined by u(0)=0 and u(n+1)=u(n)^2+z is bounded. Your definition of the M-set is wrong. – gniourf_gniourf – 2014-04-19T13:49:42.677

33Since the specification is a little bit unclear with respect to that point I can propose the following low-res ;-) 1-char php solution: * – Howard – 2011-07-06T17:32:42.463

3Well I was hoping I could just say "don't be a jerk" :D. We'll go with at least 40x30 then. – Hannesh – 2011-07-06T18:40:53.840

I have a personal preference for tasks that solve a class of problems rather than one instance. Making the region to use an input would makes this questions qualify. In any case, the specification is a bit light. In the future you can get help with these kinds of issues on the meta sandbox or the puzzle lab chat before you task goes live

Here's a source code in the shape of the mandelbrot set, which then generates high resolution mandelbrot set (http://preshing.com/20110926/high-resolution-mandelbrot-in-obfuscated-python) - OT for this question but I thought people here might like it.

Oh wow, I only just saw the code now. That is crazy! – Hannesh – 2012-05-21T12:41:35.850

2Hmm, I guess you need to pass the output to an ascii-art converter for this to count? – Paŭlo Ebermann – 2015-10-25T10:54:24.817

9@Hannesh I am a bit late to the party, but are you aware that this doesn't even meet the specs? (ASCII representation?) – flawr – 2015-10-25T20:57:10.960

1-1! It does not show the requested range: "Plot the mandelbrot set on the complex plane from (-2 - i) to (1 + i)" – None – 2016-09-14T05:39:01.760

1This is cool, and very neat. But does not meet specs, so should not have been the accepted answer. – Tally – 2017-01-14T16:35:55.233

How should I compile it? – ckjbgames – 2017-02-20T16:04:10.850

@ckjbgames The code can be assembled into an executable .com file using FASM: https://flatassembler.net/

Also, this answer does not include a byte/char count. – CalculatorFeline – 2017-05-27T03:22:57.327

9I read the code and thought it was way to short/simple to do anything interesting. 2 minutes later after sudo apt-get install dosbox; dosbox ./Microbrot.com I was found picking my jaw up from the floor. This is pretty darn impressive! – sehe – 2011-12-02T00:36:36.100

This is code golf. Don't count indentation if it isn't needed. – J B – 2011-09-29T08:06:54.303

@ JB. I updated the char count. It does not take superfluous spaces into account anymore. I have left the code indented for readability. I also tuned a parameter, the image now follows the size specification. – stackman – 2011-09-29T19:18:27.350

Python, 146 145 143char

z=lambda x,c,n:z(x**2+c,c,n-1)if n*(abs(x)<2)else x
for y in range(-15,16):print''.join(' @'[abs(z(0,x/25.+y/15j,32))<2]for x in range(-50,26))

Had to add the clause (abs(x)<2) to the conditional expression to keep Python from winging about overflows. But... this is a reason I love Sage...

BASH - 167 165 148

The mb3 file:

eval g={-4096..4096..199}'
'h={-8192..4096..99}'
x=;y=;for((i=0;i<30&&x*x+y*y<1<<26;i++)){((v=(x*x-y*y>>12)+h,y=(x*y>>11)+g,x=v));}
printf $[i%10]
'

(no trailing newline)

Run it in a terminal with line length 125:

mb3 output

BASH - 214 190

for h in {-4096..4096..200};do
for g in {-8192..4096..115};do
x=0;y=0
for((i=0;i<30&&x*x+y*y<1<<26;i++));do((v=((x*x-y*y)>>12)+g));((y=((x*y)>>11)+h))
x=$v
done;printf $[i%10];done;echo;done

This basically is the same code like below with calculations being replaced by hardcoded values and the image got flipped around the x axis.

mb2.bash run snapshot

The version below did not fully fit the rules breaking "from (-2 - i) to (1 + i)".

BASH - 263 261 260 236

Use this source, Luke:

a=-8601;b=2867;c=-4915;d=4915
((e=(b-a)/99));((f=(d-c)/49))
for((h=d;h>=c;h-=f));do
for((g=a;g<=b;g+=e));do
x=0;y=0
for((i=0;i<30&&x*x+y*y<1<<26;i++));do((v=((x*x-y*y)>>12)+g))
((y=((x*y)>>11)+h));x=$v
done
printf $[i%10]
done;echo;done

This code uses integer arithmetic only, so BASH does not need additional helpers for doing floating point maths...

mb.bash run snapshot

In arithmetic evaluations Bash casts the empty strings to 0, so is enough to initialize x=;y=. Shift operators have lower precedence than addition and multiplication, so no need for parenthesis around >>'s left side operand. And you can use {…} instead of do…done, like Digital Trauma advises in his tip. And you can put multiple expressions in an arithmetic evaluation, just separate them with ,.

@manatwork ... thanks! ;-) – None – 2016-09-14T10:06:26.040

You forgot a pair of parenthesis in (x*x-y*y)>>12. They change nothing. – manatwork – 2016-09-14T10:17:15.823

Yes... it looks sooo mean without the parenthesis... I kinda didn't dare it... :-/ – None – 2016-09-14T10:35:22.223

Nice. I tried this approach: GraphicsGrid@ImageData@Binarize@MandelbrotSetPlot[ImageResolution->40]/.{1->" ",0->"*"} but it was 84 characters and the output is not as nice as yours anyway. – Michael Stern – 2015-10-25T16:17:53.413

Here's a coffee-script answer running on node.js: In black and white:

m=(x,y)->
 a=x
 b=y
 z=0
 for i in [0..99]
  (return if i>60 then '*' else if i>10 then '-' else if i>5 then '.' else ' ') if z>4
  l=y*y
  z=x*x+l
  y=2*x*y+b
  x=x*x-l+a
 '@'
console.log (m x,y for x in [-1.5..0.5] by 2/79).join '' for y in [-1.3..1.3] by 2.6/40

ascii_mandel_color

Adding color:

n='\u001b[0m'
m=(x,y)->
 a=x
 b=y
 z=0
 for i in [0..999]
  (return if i>100 then '\u001b[33m*'+n else if i>10 then '\u001b[34m-'+n else if i>5 then '\u001b[31m.'+n else ' ') if z>4
  l=y*y
  z=x*x+l
  y=2*x*y+b
  x=x*x-l+a
 '\u001b[32m@\u001b[0m'
console.log (m x,y for x in [-1.5..0.5] by 2/79).join '' for y in [-1.3..1.3] by 2.6/40

Perl, 153 chars

for(-21..20){$y=$_/20;for(-60..18){$r=($x=$_/30);$i=$y;for(1..99){$t=$r;$r=$r**2-$i**2+$x;$i=$t*$i*2+$y}if($r**2+$i**2<4){print"X"}else{print$"}}print$/}

Output: I can't post a picture because I am a new user, so I will try posting the text of the output.

C# - 304 Chars

When I code, I code with readability and beautiful formatting. I threw up writing this.

using C=System.Console;class Program{static void Main()
{C.WindowWidth=220;C.WindowHeight=80;
int w=220,h=80,m=100;double s=4.0/w,v=4.0/h;
for(int i=0;i<h;i++)for(int j=0;j<w;j++){
double n=s*j-2,u=v*i-2,x=0,y=0;int r=0;
for(r=0;x*x+y*y<4&&r<m;r++){
double t=x*x-y*y+n;y=2*x*y+u;x=t;}
C.Write(r>=m?'#':' ');}C.ReadLine();}}

I am sure my solution can be improved but for reference I shall post it. Note that the windows console squashes the image.

Haskell: 340 char

Well, as I see no haskell answer, I post mine, I tried to minimize it from what I have done so far. I am sure I can reduce it a lot. But here is the first try:

m (x,y) (z,t)=(z*x-y*t,y*z+x*t);
a (x,y) (z,t)=(x+z,y+t);
r=1.0
f c z 0=z
f c z n=f c (a (m z z) c) (n-1)
e (x,y)=sqrt(x*x+y*y)
t c=(e(f c (0.0,0.0) 32)) < 2
b=map (\z -> (t z, (fst z > r-0.01))) [(x,y) | y <- [-r,-r+(1.0/15)..r], x<-[-2*r,-1.96..r]]
s True="\n"
s _=""
g (b,c)=(if (b) then "@" else " ")++s c
main=putStrLn$concat$map g b

And here is the result:

                                                  @

J, 70

3 :'try.2>|(y&+&*:)^:32[0 catch.0 end.'"0(1-~15%~i.31)j.~/2-~13%~i.40

Displays members of the set as 1, the rest as 0. Spaces each computed point two characters wide, so as to keep a mostly-square pixel with most fonts.

QBasic, 222 Characters. Not that short, but QBasic is a pretty verbose language. Also, I updated with a seemingly more correct version

FOR y=1 TO 23
FOR x=1 TO 80
a=0:b=0
c=-2.5+(x/80)*3.5:d=-1+(y/23)*2
FOR i=0 TO 1000
IF a*a+b*b>=4 THEN GOTO E
t=a*a-b*b*c:b=2*a*b+d:a=t
NEXT
E:LOCATE y,x
IF a*a+b*b<4 THEN
?("@")
ELSE
?(" ")
END IF
NEXT
NEXT

Output is as in the following image.

SpecBAS 201

I know this one is an old question, but we've been playing with Perlin's ascii brot in the BASIC programming forum, and here's mine - in SpecBAS (which is a kind of Sinclair BASIC interpreter) and it really is just text, and one line of code:

1FOR y=-29TO 30:FOR x=-10TO 89:LET m,r=0:FOR k=0TO 224:LET j=r^2-m^2-2+x/25,m=2*r*m+y/25,r=j,l=k,k=IIF(j^2+m^2>11,225,k):NEXT k:PRINT INK l;"ð";:NEXT x:NEXT y

Output: SpecBAS ascii mandelbrot

The output should be in ASCII. (And you can write e.g. any Java program in one line.) – flawr – 2015-10-25T21:00:57.487

Highest voted entry was not ASCII. – ZXDunny – 2015-10-26T08:00:15.520

@flawr Ok, here's the "ascii" version (176 bytes) - and the reason I was quite pleased about it being on one line is that it isn't actually Java... 1FOR y=-29TO 30:FOR x=-10TO 89:LET m,r=0:FOR k=0TO 112:LET j=r^2-m^2-2+x/25,m=2*r*m+y/25,r=j,l=k&15,k=IIF(j^2+m^2>11,113,k):NEXT k:PRINT" .:-;!/>)|&IH%*#"(l+1);:NEXT x:NEXT y. – ZXDunny – 2015-10-26T08:46:31.430

You should put that version in the answer. – CalculatorFeline – 2017-05-27T03:28:14.690

Try it online!

This is a Mandelbrot renderer that I implemented a couple of years ago for a Rosetta Code submission. Since Befunge has no floating point, it uses a form of 14-bit fixed point arithmetic emulated with integer operations. It has a maximum of 94 iterations with the ASCII character set as the "palette".

This was originally implemented with portability in mind rather than size, but it should still be reasonably well golfed as it is.

c++-11 -- 298 characters

Fully golfed, unparameterized version that does only what is required:

#include <complex>
#include <iostream>
#define C complex<float>
using namespace std;int main(void){C p(-2,1),q(1,-1);char i,j,k;
for(j=0;j<30;++j){for(i=0;i<80;++i){C r=q-p,c((i+0.5)*r.real()/
81+p.real(),(j+0.5)*r.imag()/31+p.imag());r=0;k=64;while
(abs(r)<=2&&(--k!=32))r=r*r+c;cout<<k;}cout<<endl;}}

The implementation is completely unremarkable. Just seeing what can be done using the native complex time (which is, alas, a little wordy).

Ungolfed and parameterized so that it can do regions

#include <complex>
#include <iostream>
using namespace std;
void M/*andlebrot*/(ostream& o, 
            complex<float> p, complex<float> q, 
            int l, int h) {
  char i,j,k;
  for(j=0; j<h; ++j){
    for(i=0; i<l; ++i){
      complex<float> r=q-p,c((i+0.5)*r.real()/(l+1)+p.real(), 
                 (j+0.5)*r.imag()/(h+1)+p.imag() );
      r=0;
      k='@';
      while(abs(r)<=2&&(--k!=' ')){
        r=r*r+c;
      }
      o<<k;
    }
    o<<endl;
  }
}

int main(int argc, char*argv[]){
  M(cout,complex<float>(-2.15,1.25),complex<float>(0.65,-1.25),80,30);
}

20{40{0.1{.{;..*2$.*\- 20/3$-@@*10/3$-..*2$.*+1600<}*}32*\;\;@@(}60*;(n\}40*;

It can probably be golfed a lot more. The result is an approximation because I have to use integers.

1So it's not yours? Might be good to say who's it from. – Camilo Martin – 2014-01-20T01:16:50.643

Python, 115.

r=range
for _ in r(-11,12):
 for f in r(-39,41):
  v=u=f/22.-_/11j;exec"u=u*u+v;"*40;print"\b"+chr(32+(u.real<4)),

Works only on 80x24 terminals, but you can add print after first for to fix it.

Sample output (With additional print instruction.):

                                       !

                                  !!!!!                                         
                            !  ! !!!!!!!! !

@Doorknob It wasn't copied directly from anywhere, it's a very popular program and I can't find who originally wrote it. (buf if you have the link/name I'll be happy to put it in) – MD XF – 2017-05-27T01:21:42.247

Source. – MD XF – 2017-05-27T00:18:00.037

Since you've taken the code from elsewhere you should probably make this answer a Community Wiki. – Post Rock Garf Hunter – 2017-05-27T00:37:49.793

1@WheatWizard I remember Dennis saying on TNB last night that doing so is unnecessary. – MD XF – 2017-05-27T00:38:22.473

1It is not necessary. There will not probably not be any repercussions for not doing it. I'm just suggesting it because I think its the right thing to do. Its ultimately your choice. – Post Rock Garf Hunter – 2017-05-27T00:40:38.133

1@WheatWizard I guess it is a bit douchey to possibly get rep for something I didn't write. But there's a meta post by DJ talking about how CW isn't a rep waiver. – MD XF – 2017-05-27T00:41:38.457

I definitely agree that community wiki is not a rep waiver. The only thing I'd change here is including the link to the source in the answer (as comments are not guaranteed to stay around) – trichoplax – 2018-09-19T18:38:54.100

you included math for sqrt(x^2+y^2) < 2. You can compare with 4 and remove the sqrt and the include. – ilmale – 2014-04-22T00:58:01.437

which though isn't really short,
is one line which is pretty boss.

Explanation

This takes advantage of Python's internal handling of complex numbers, so I can just do 1~12$:; (the equivalent of (-1)**0.5 in Python) to get the imaginary unit. Then there are three nested For loops, which loop through y, x, and z=z^2+c. Breaking out of the innermost loop is necessary (and done by d$~2`9&) because otherwise, numbers will get so large that they become (NaN+Nanj), which apparently has a magnitude less than 2.
