RES: [Dev-C++] Code for all combinations

[<and...@su...>]

Yes! It is.

I am working with genetic algorithms (programming thechnique
that mimics the biological behavior to solve the problems.
A "Darwinian" way to do that. A random set "population" of
candidates of solution begins with mutations, reproductions,
cross-overs, etc, to find the best family of solutions and
its best representant. It´s a sthocastic/heuristic way to
solve NP-hard problems) and I am interested to compare
a simple combinatorial analysis with the GA method. The simple
combinatorial analysis program will test all the
10*10*10*10*10*10=10^6 possible results. With the results
I will make some graphical comparisons.
Fishing this phase, I will need to develop some advanced
"cross-over" techniques.
Finishing this other phase, I will need to apply theese
results in a FPGA digital filter of specificy frequencies.

Thank you
Andre

Hi,

just curiosity, is that a school assignment?  An idea would be to nest six
for statements.

Dear Users,

   I need to test all possibilities in a specific code.
   I couldn´t realize how I can generate theese possibilities with two
for´s.
   Here is the problem:

   Suppose you have a vector like
   int vect[6]={0};

   How could be a C code to have (print for example) all possible
combinations in the
six positions from the range 0 to 10?
the output is something like:
   0 , 0, 0, 0, 0, 0
   1 , 0, 0, 0, 0, 0
   2 , 0, 0, 0, 0, 0
   ...
   10, 0, 0, 0, 0, 0
   0 , 1, 0, 0, 0, 0
   0 , 2, 0, 0, 0, 0
   ...
   0 ,10, 0, 0, 0, 0
   1,  1, 0, 0, 0, 0
   2,  1, 0, 0, 0, 0
   ...
   10, 1, 0, 0, 0, 0
   1 , 2, 0, 0, 0, 0
   2 , 2, 0, 0, 0, 0
   ...
   10, 2, 0, 0, 0, 0
   ...
   ...
   10,10,10,10,10,10

   Some repetition values are allowed, that is, if you have to
reset all values to begin the counting to another digit, etc.

Regards
Andre
