Hi all,

I have my code here i tried sevral time with many suggetuon between break and while loop but keep running with no stop.

I need to test all element in nodes lalel to meet the conditions and then if the node label set meet the condition stop and give me answer(it sould test all the for loop). node label is the random perm.

this my matlab version (MATLAB : Version 9.10 (R2021a))

code:

    nodeslabel=[0,randperm(4)]
 for i=1:n
      for j=1:n
           if i~=j 
                if % condition met (print)
                else  
                    % exist the all if condition and for for loops and make
                    % new nodeslabel=[0,randperm(4)] till if conditon met 
                 end
           end 
      end
 end

This code:

nodeslabel=[0,randperm(4)]
for i=1:n
    for j=1:n
        if i~=j 
            if % condition met (print)
            else  
                % exist the all if condition and for for loops and make
                % new nodeslabel=[0,randperm(4)] till if conditon met 
            end
        end 
    end
end

does not have a while loop and will not be an infinite loop unless n is infinite. Either post the actual code with a while loop in it, or step through it with the debugger. Evidently you're not debugging your code by stepping through it line by line and I'm wondering why not.

In your code, [while ... loop] has to be eliminated and then everything else works ok.

% while true  % To be eliminated
...
    
% end

then there must be the condition to set while operator to halt, e.g.:

Halt = 1;
while Halt == 1
 ...
    % Condition is met
 Halt = 0;
end

I've tried that unfortunatly doesn't do the process again and give me the sol when the condition met.

I really want same this idea after else and if ...

    nodeslabel=[0,randperm(4)]
 for i=1:n
      for j=1:n
           if i~=j 
                if % condition met (print)
                else  
                    % exist the all if condition and for for loops and make
                    % new nodeslabel=[0,randperm(4)] till if conditon met 
                 end
           end 
      end
 end
