MAZE Problem

Hi every1

I have a code here to create a 2 dimensional array Maze with Food and Space.
1= Food 0 = space

Is it possible to make it randomly generate food in the array instead of pre-positioning??

It will be showing by web browesr. Any recommandation?
thanks

Thanks
I have not included the XML tress, coz dont want to mess up the post
thanks

Code:

---

int run;
char filename[16];
FILE *filep;

char *nodep;
int row, col, next_row, next_col, heading, steps, pellets;

it is possible using loops and rand function for example

Thanks for your Help

But you have some simple example?

this was my first post and reply within 10 mins This is amazing

Um, what sort of pattern do you want to use. I mean, if you just want to scatter food all you have to do is:

Code:

---

for (c = 0; c < 100; c++) matrix_data[rand()&#37;MATRIX_SIZE][rand()%MATRIX_SIZE] = 1;

---

This assumes c has been declared as an int, you've already filled the array with 0s, and you've included <stdlib.h> and run srand() at some point. This also assumes you don't care about the fact that you'll actually have less than 100 foods at a given time due to overlaps and this assumes that you don't want those nice little line patterns you've got going on there.

Now if it's a sort of maze generation you'll have to make something a little more robust.

Code:

---

#include <time.h>
#include <stdlib.h>

void intimatrinx( char matrix_data[MATRIX_SIZE][MATRIX_SIZE])
{
        int i;
        int j;
        srand((unsigned int)time(NULL));

        for(j=0;j<MATRIX_SIZE;j++)
          for(i=0;i<MATRIX_SIZE;i++)
          {
                  int res = rand()&#37;5;
                  matrix_data[i][j] = (res ==0);
          }
}

You guys reply speed is so FAST
Thanks every1

I will have a go now and see does it work
Once i have test I will post back
thanks


Thanks

Yup, this is a very active board.

Just thought I'd add this: since you appear to be wanting paths of 1s, just generating them randomly isn't going to give you a very satisfying result. As guesst said:

Now if it's a sort of maze generation you'll have to make something a little more robust.

---

To generate "paths", consider picking a random starting position, and a length from say 5 to 50. (You could make shorter or longer paths more common if you wanted to -- more on that later.) Then pick a direction and draw 1s in that direction until you get to the length you wanted. You could turn every now and then, say on a 15&#37; chance.

I'm not sure if that's what you're looking for so I won't explain any further.

i saw you website which saying you produce the program with maze selector under 24 hr you must start programming long long time ago...

Oh, that. :) Yes, I've been programming for quite some time . . . but it's not really a very difficult type of program to create. tmaze doesn't generate mazes, either -- they're all hard-coded. I did write another program that generated maps, but I never uploaded it. Generating maps like I think you're trying to do is a quite a bit harder.

tmaze was designed to run on a 4MHz (that's four megahertz!) laptop, which is why it uses DOS code and stuff like that. Looking at it now, it's not very well written, actually. :)

I am not trying to generate a map
I am make a mouse to eat food place somewhere on the map.
Not necessary a path.
Concentrate on how it is going to choose the food

once again
thanks 4 quick quick reply

Have tried both code, but didn't come up any food on the map.
Any idea wt else do i need??
cheers

Accessing array elements in column-major order.. in C? Bad Vart!

And of course, a little more on topic:

Yes. Debug your code. How do you even know it isn't working? Are you sure you're printing the array properly? Are you printing the right array?

Unfortunately, we can't debug your code for you.

The closest food or something?

Thanks for every1's help again.

This is meant to be genetic programming. The mouse will choose the food.
The animation will be showing in SVG format and XML
The program was working when it had a map like my 1st post. However after my last night's modifaction, it's stop working.

Do i need to place 0's first and how???

How do i add the srand()??
Thakns Thanks

any good site recommand for XML and SVG???
thanks

You can fill a chunk of memory with memset(something, 0, sizeof(something)) - if something isn't an array, you need memset(&something, ...) [the rest stays the same].

Sorry, can't help with XML or SVG.

Okay, I noticed in your original code that the food data was kept in the matrix_data array, but that the print_matrix function used the trace_matrix for it's output. I assumed there was something we weren't seeing where you copied the matrix_data into the trace_matrix, tho that's not shown in the code snippet.

In other words, of course you don't see what we've done because our code filled matrix_data and your code prints trace_matrix. You've got so many matrix variables, is it possible you're confusing yourself? (And what in the world did you show us print_program function for?)

Really going no where ..................

thanks every 1

I have followed what guesset given, but i really confused ..

Cheers

double temp = seed * a;
And where is the seed initialized?

do you have any main? I do not see what is the flow of your program
do you need all this scaring global vars appearing here and there?

do you know how to comment your code to bring a little light into the dark room?

Sorry Have attaced the file...
Coz too large to place here.
hope you have time take a look.

I have modify the code, but it is........
"::><::"

1) What is your problem?

2) I looked at your code and you have one of the most aggravating coding styles I've ever seen.

I'm assuming that you're still trying to fill your matrix with random data. I looked at your code, and NOWHERE is either matrix_data or trace_matrix referenced by anything useful. There doesn't even seem to be an attempt to fill either of them with random data. So I guess I'm a little confused on what you want help with...

oooo I think i was too sleep and depress so just put some bull ........ in....

Really Sorry

If you have chance too look at the original code, it is working already and able to compile and see the result...


But now I am trying to randomly fill 1s and 0s on the map.

but i will specificy 100 food is being place, So do i still need the srand()?

Code:

---

for (c = 0; c < 100; c++) matrix_data[rand()&#37;MATRIX_SIZE][rand()%MATRIX_SIZE] = 1;

---

how do i expand this code??
thanks
thanks evey1

Even my Hat is unable to guess what you think you mean by "expand this code". It does just what it says it will: every time through the loop, it will set matrix_data[some random row][some random column] to 1. The only reason you might not be getting 100 pieces of food is if you happen to pick the same row and column in loop number 84 as you did in loop number 37. If you want to be sure there are 100 pieces of food there, you need to check if there was food there already (quick and dirty way: increment your matrix_data element, and if it's bigger than 1, decrement it back down and decrement c as well).

wt you mean is food is already therer? but just not sure the mouse eat that or not??

If i can successfuly computer the random array does it affect the XML tree or i need to do the XML tree again??

Thanks thanks

What really amazes me is that you have 700 lines of genetic algorithm code, but you can't fill an array with random values. Something just doesn't seem right...

You have to finish making the grid before you can do anything else. You start with 0's everywhere, and you (claim you) want to put 100 1's in the grid. There is no mouse, or XML, or anything else, in the problem.

What XML tree? I don't even think the phrase "XML tree" makes sense. If you mean the XML markup that you print your data in, of course the XML markup doesn't change.

the code is not from me, but i need to modifiy it to something similr.
First i need to change it to random food map.
Secondly i need to change the GUI

and find a way to show it by SVG in IE

HAAHAH thanks 700Line of code of course is not from me. I won't say it is mine.

tabstop I really thanks for your help.

So i need to leave the array in all 0's? and put 1 in from the function??

thanks

If by "function" you mean "that one line of code upthread that had a for-loop in it", yes. Initialize to 0's instead of the pattern you have, and use the for loop to put 1s in it.

---

Make sure you have a plugin, then. Firefox can display SVG images by itself, but Internet Explorer needs a plugin. http://wiki.svg.org/Internet_Explorer

By the way, you can initialize every element to zero with

Code:

---

char matrix_data[MATRIX_SIZE][MATRIX_SIZE] = {{0}};

---

because any unspecified elements are set to zero. Or you could just leave it, because global variables are initialized to all zeros by default. That's probably not a good idea, though. Try the code I have just above.

DWK~~Thx so much

Have reduced the code replaced by yours haha.. I am so stupid ~ ~

Anyway can you give me a little bit more hint how to place the 1's??
thanks thanks

can any1 can tell m what's gone wrong????

Hi the code is working now.

Code:

---


////create array map 32 X 32 (1024 steps) with all zeros and trace map////
int matrix[MATRIX_SIZE][MATRIX_SIZE];
int matrix_data[MATRIX_SIZE][MATRIX_SIZE] = {{0}};
int trace_matrix[MATRIX_SIZE][MATRIX_SIZE];

///////////////////////////////////////////char to int//////////////
void output_program(struct prog *progp)
{
  char *codep = progp->code;
  int token;

  while (token = *codep++)
    fputs(token_table[token].name, stdout);
  putchar('\n');
}

int main()
{
  int i; time_t start;

  seed = time(NULL);
  time(&start);

Now the program produce a random map. But how can i ensure food do not overlap??

In addition, is it able to create 1 random map and 2 maps to allow user to choose? and how can I implement it?
thanks

Watch carefully; there may be a test afterwards:

Code:

---

for (c = 0; c < 300; c++) {
    int x = rand()%MATRIX_SIZE;
    int y = rand()%MATRIX_SIZE; //our x- and y-coordinates
    matrix_data[x][y]++; // add 1 to our randomly chosen spot
    if (matrix_data[x][y] > 1) { // oops!  too much!
        matrix_data[x][y] = 1; //reset food
        c--; //take away from the count of food
    }
}

---

I cant belive you ability so fast......
It runs perfet!!!!

You know the array I have creted... can you hint me why it kept error pleasE??

Code:

---


int matrix[MATRIX_SIZE][MATRIX_SIZE];
int matrix_data[4][MATRIX_SIZE][MATRIX_SIZE];
{   

    cout <<"Ender Maze wanted:";
    cin >> x;
    cout <<"Maze Choosen is: " << x << endl <<endl;


    matrix_data[0][MATRIX_SIZE][MATRIX_SIZE] = {{0}};
    matrix_data[1][MATRIX_SIZE][MATRIX_SIZE]= {{1}};
  //  //--------------------------------------------------------------//
  //  //--------------------------------------------------------------//
    return matrix_data[0];
}
int trace_matrix[MATRIX_SIZE][MATRIX_SIZE];

---

in the main

Code:

---

int main()
{
    int n;
    for (n=0; n<4; n++);
        //result += matrix_data[n];
    printf("%d\n", matrix_data[n]);
    //std::cout<< matrix_data <<std::enl;
    //cout << result
   
    return 0;

---

I think I am completely wrong in the int main()
wt statement i need to read the array and put it back?

Thanks for you Great Help X 10000000000

You can only use an array initializer when you declare it, so this line:

Code:

---

matrix_data[0][MATRIX_SIZE][MATRIX_SIZE] = {{0}};

---

(and the one after it) are errors.

To initialize a matrix, you need to run a double for-loop. So, for instance, to initialize matrix_data[0], we would run a for-loop on row, and inside that a for-loop on col, and inside that we would set matrix_data[0][row][col].

Alternatively, you could do one big initializer as so:

Code:

---

matrix_data[4][MATRIX_SIZE][MATRIX_SIZE] = {
{{0}}, //this is matrix_data[0], the random one
{{0,1,1,0,1,1,0,0,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0}, //this is first row of [1]
 { ...stuff ...}, //the second row of [1]
 { et cetera },
 { and so on}} //end of [1]
{{more numbers}, //first row of [2]
.
.
.

---

It will be big, but if you've got them already you can copy'n'paste.

These are what I have mdify:

Code:

#include <iostream.h>
#include <fstream.h>
#include <iomanip.h>

Like you said it's gonna be huge if 3-4 maps existed. So ihave only include 1 random map and 1 pre-defined map.

But where do i use the double- for loop?? and what should i include in the main?

What i am currently in the main isn't very usefulllll

Code:

---

int main()
{
    int n;
    for (n=0; n<4; n++);
        //result += matrix_data[n];
    printf("&#37;d\n", matrix_data[n]);
    std::cout<< matrix_data <<std::enl;
    //cout << result
   
    return 0;

---------------------------[thanks for the Help]--------------------------------

Code:

---

    matrix_data[1][MATRIX_SIZE][MATRIX_SIZE] =
  { {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},

  ....
  };

---

Won't compile - it's not possible to initialiize the variable once it's been declared - it has to be on this line:

Code:

---

int matrix_data[2][MATRIX_SIZE][MATRIX_SIZE];

---

Edit: and of course you need to initialize both at the same time.

So, wherever you set up the random matrix, that's where you set up the other pre-defined matrix as well.

Hi Mats I am sorry can you explain further what do i need to change??

you mean i have to change from:

matrix_data[1][MATRIX_SIZE][MATRIX_SIZE] =
{ {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ,0,0,0,0,0,0,1},
{0,1,.....
[/code]

to

Code:

---


int matrix[MATRIX_SIZE][MATRIX_SIZE];
int matrix_data[2][MATRIX_SIZE][MATRIX_SIZE];
    cout <<"Ender Maze wanted, 0,1,2,3:\n";
    cout <<"    0- Random Maze\n";
    cout <<"    1- Set Maze (1)\n";
    cout <<"    2- Exit\n";
    cin >> x;
    cout <<"Maze Choosen is: " << x << endl <<endl;
   
    matrix_data[0][MATRIX_SIZE][MATRIX_SIZE] = {{0}};
    matrix_data[1][MATRIX_SIZE][MATRIX_SIZE] =
  { {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
    {0,1,0,0,0,0

---

or sth else???? Cheers



[code]

tapstop ic

So i should put the pre-define matrix inside the
int main()?

I mean "something else".

You have variable declaration (int matrix_data[...][...][...];), and then you attempt to assign this variable using an initializer list somewhere else. That is not valid code.

Simple example:

Code:

---

// Valid code:
int arr[10] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
// Not valid code
int arr[10];

arr = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

---

Mats

This is the problem; coz i am try to store differetn 32 X 32 matrix.
therefore in my array have 2 maps.

I can't not just put 1 number.
So how can i resolve this???

or like this?

Code:

---


int matrix_data[2][MATRIX_SIZE][MATRIX_SIZE]; = { {{0}}, {{1,1,1,1,1,0,0,0,0,0,0,},{1,1,1,0,0,0,0,1,1,0}};}

This is your declaration. The only only only only place you can do an initializer is here. Only here. Anywhere else, and you'll have to access the array elements one-by-one.

---

---

This is the one you want. You have to initialize the whole thing in one shot with an initializer list like this.

I am confused...XX.....

But how can i add element into this???
like above??


..... sorry

i think i figure out now hahah
thx thx

I have an example posted already. You have one array -- it has three dimensions. If you're going to initialize it, you have to do it now, when you declare it, and you need to initialize it all (or at least everything you plan to do). So do so. We're going to do the random one later, but we need all 0's so:

Code:

---

{
{{0}},

---

Then you need the first array; copy and paste the whole thing in from

Code:

---

{{ lots of numbers up to}}
}

---

. And there you are.

Code:

---

int matrix[MATRIX_SIZE][MATRIX_SIZE];
int matrix_data[2][MATRIX_SIZE][MATRIX_SIZE]; ={ {{0}},

{ {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},

    {0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0},

return matrix_data[0];
int trace_matrix[MATRIX_SIZE][MATRIX_SIZE];

these should make sense?


What i need to write in the int main() ?

i think i need to allow the user input and read the data from the array and output.

I am trying to produce the code, but it comes more than 15 errors.

Wt else do u need to modify????






-----------THX---THX-------------

Code:

---


int main()
{
    cout <<"Ender Maze wanted, 0,1,2,3:\n";
    cout <<"    0- Random Maze\n";
    cout <<"    1- Set Maze (1)\n";
    cout <<"    2- Exit\n";
    cin >> x;
   
    return 0;

---

I have put these into the int main() What else is missing? Or i need to define other function??
plz help

cheers

Who knows what's missing? This doesn't do anything apart from: printing a menu, and getting a choice back. Everything else you want done, you have to do.

OIC
This is what i though coz they dun read the input and get the output.
so i need to create a function for the data to process!?

So i need specific 0 is to choose the map [0]
and 1 i choose map[1]??

for(int maze=0; maze<3 ; maze++)
cout<<matrix_size[maze]<<"------"<<matrix_data[n]<<endl;
these should put inside the int main() or void()??


I am really sorry for all these......

You can do it inside main directly, or put it another function, as you wish; but if you put it in another function you do have to call that function from main, or else it won't happen. Notice that there is no function called void().

Sorry
So i think i will put them inside the main...

I have seen the other tread you reply
using printf and scanf

are they more useful for me?? (I know it sounds weired)

I will use that method to see does it get me anywhere.Thanks

I am sorry for all these question, but i really trying to get them work, I have not stopping on these since you repled me this morning ahahaha.

---------Thanks God------------

I have done the following changes in the int main()

Code:

---

int main()
using namespace std;
{
   
    int maze;
   
    cout <<"Enter Maze wanted, 0,1,2,3:\n";
    cout <<"    0- Random Maze\n";
    cout <<"    1- Set Maze (1)\n";
    cout <<"    2- Exit\n";
   
    cin >> maze;
    {
    for (maze =0; maze < matrix_data[n]; maze++)
        cout<<matrix_data[n] <<endl;
   
}

---

still 3 errors, any 1 can point out wt's going on????
Thanks Thanks

The three errors tell you exactly what's going on:
unclosed brace on line "{" (right after cin >> maze)
variable n not defined
unable to compare int (maze) with int[][] (matrix_data[n]) (although your error might say something about conversions from int[][] to int)

Not a compile error, probably, but cout << matrix_data[n] will probably print out a hex memory address, since matrix_data[n] decays into a pointer.

Still getting syntax error

Code:

---

int main()
using namespace std;
{
    int maze[][], n;
   
    cout <<"    Enter Maze wanted, 0,1,2:\n";
    cout <<"    0- Random Maze\n";
    cout <<"    1- Set Maze (1)\n";
    cout <<"    2- Exit\n";
   
    cin >> maze[][];
    matrix_data[n] =maze[][];
    {
    for (maze[][] =0; maze[][] < matrix_data[n]; maze[][]++)
    cout<<matrix_data[n] <<endl;
    printf("%d\n", matrix_data[n]);
    return 0;
}
}

---

i am also having error on this line....

Code:

---

int matrix_data[2][MATRIX_SIZE][MATRIX_SIZE]; ={ {{0}},
{ {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
    {0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0},
    {0,

also wt this mean?

"unable to compare int (maze) with int[][] (matrix_data[n]) "

Does the initializer continue after the 0, ? You can't just stop.

And the last means what it says: you can't compare (using < for less than) an integer to a matrix. What would that mean?

Code:

---

              .
              .
              .
              .
,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0},
    {0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0},
    {0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0},
    {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1}
  };}

return matrix_data[0];
int trace_matrix[MATRIX_SIZE][MATRIX_SIZE];

void output_program(struct prog *progp)
{
  char *codep = progp->code;
  int token;
   
    while (token = *codep++)
    fputs(token_table[token].name, stdout);
  putchar('\n');
}


void print_matrix(void)
{  int i, j; char symbs[] = " OX";

  for (i=0; i < MATRIX_SIZE; i++)
  {  for (j=0; j < MATRIX_SIZE; j++)
          putchar(symbs[trace_matrix[i][j]]);
      putchar('\n');
  }
}

---

This is the end of it....

Code:

---

for (maze[][] =0; maze[][] << matrix_data[n]; maze[][]++)

---

So aboe must be wring...

If i can't use integer to a matrix,,,, so how can i retrieve the data?

Thanks Thanks

Notice in your initializer that you've embedded the semicolon in the thing, rather than being at the end like it should.

This is so amazingly wrong that it makes me give up hope.

matrix_data is a 3-dimensional array.
matrix_data[0] is a 2-dimensional array (namely, a map).
matrix_data[0][1] is a 1-dimensional array (specifically, the second row of the map).
matrix_data[0][1][2] is an integer (the third number in the second row of the map).

You can only deal with specific elements of the array.

oooooooooo

so all code are wrong ?
or I need to find a different way to do it?

cheers

I hadn't looked at the stuff you had added from the previous error post to this one. Yes, every single line of code you added from x:32 to (x+1):02 (x depends on your time zone) is wrong, and cannot be made right.

Find a C++ book. Start on page 1. By the time you get to page 200 or so, this will all seem much easier.

I don't think I have that much time.....
I only have 30 days left for this .
and i need to find a way to display the animation on the browser in SVG format.

I will move on to this tomorrow
tabstop. Thanks for your every great help and attempt. Without your help I wouldn't get the map done.

Thanks

You could compress your map data. I'm not suggesting anything radical, something simple like keeping track of alternating runs of 0 and 1, then write a function to populate the map from the data. So like your matrix data:

Code:

---

  { {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
    {0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0},
    {0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0},
    {0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0},
    {0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0},
    {0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0},
    {0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0},
...

---

etc
would be reduced to :

Code:

---

    {0,1,30,1,2,1,28,1,3,26,1,5...}

---

etc. (Note, I started with the assumption that the first bit would be 0. In this map that wasn't the case, so I had to start with a 0.)

This would effectively reduce the map in memory to a more manageable size. Treat the whole map like a single line and just be sure to wrap around your data structure appropriately. (By the way, this is a similar method used in the classic BASIC program LOVE.)

I recently came up with a more robust method of compression, but I don't think this program calls for that.

Hi
thanks every1
Finally i got code working now.

I am wonder, is it possible to leave a colour path on the maze, where the ant has been?
and I Am looking to create fix point for the ann to start with and end at the other fixed point
thanks thanks

also my program does create a XML file, but i really duno how to show it under SVG
any1 had such experience?
thanks

the colour problem has been solve now


But how can i get it start and end in a fixed point.
Also any1 can explain what is mutation in genetic programming
please
thanks thanks
