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.

Since the specification is a little bit unclear with respect to that point I can propose the following low-res ;-) 1-char php solution: * — Howard, Commented Jul 6, 2011 at 17:32
Well I was hoping I could just say "don't be a jerk" :D. We'll go with at least 40x30 then. — Hannesh, Commented Jul 6, 2011 at 18:40
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 — dmckee --- ex-moderator kitten, Commented Jul 6, 2011 at 19:16
@Hannesh, I agree with dmckee. If you change the question, I'll be happy to add arguments. — boothby, Commented Jul 7, 2011 at 0:01
Here's a source code in the shape of the mandelbrot set, which then generates high resolution mandelbrot set (preshing.com/20110926/…) - OT for this question but I thought people here might like it. — DanBeale, Commented Oct 1, 2011 at 11:54

C, 988 chars

Here's mine, which does an ASCII mandelbrot, written as an ASCII mandelbrot, in C.

Oh.. and it also has interactive zoom functionality. (press the keypad numbers 1-9 to zoom in on the respective area)

This is code golf. Don't count indentation if it isn't needed. — J B, Commented Sep 29, 2011 at 8:06
@ 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, Commented Sep 29, 2011 at 19:18

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:

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.

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...

\$\begingroup\$ 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 ,. \$\endgroup\$

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

\$\begingroup\$ 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. \$\endgroup\$

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:

\$\begingroup\$ The output should be in ASCII. (And you can write e.g. any Java program in one line.) \$\endgroup\$

\$\begingroup\$ @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. \$\endgroup\$

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.):

                                       !

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.

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.

Here's one from the python developers,
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.
