How to plot an iteration to run like a simulation while iteration is still ongoing?

if k = T > 0
    if MaxTime > elaspedtime
             Cur = 10;
             Best = Cur;
             ECur = exp(Cur);
             EBest = exp(Best);
             tic;
                for subit = 1:Maxsubiterations
                    New = randi([1 100000]);
                    ENew = exp(New);
                    CE = ENew - ECur;
                    if CE < 0
                        Cur = New;
                        if ENew < EBest
                           Best = New;
                        end
                    else
                        P = exp(-CE/T)
                        R = randi([0 1]);
                        if R < P
                           Cur = New;
                        end
                    T = alpha*T
                    if T<=0
                        break
                    end
                    end
                end
              toc;
             elaspedtime = toc;
    else
    break
    end
end

How can i plot the variable Best for each iteration like a simulation as the iteration runs?

You have one too many ends in your code.

Not sure at what point you want to plot Best, and against what other variable, so here's a simple example that might help.

X=0;
Y=cos(X);

while X<2*pi
    X = X+.1;
    Y = cos(X);
    
    plot(X,Y,'o')
    hold on
    
end
hold off

hi, i've tried your code and i actually meant for each iteration to plot one one by one like a simulation? yes I notice the extra ends. I have edited the code.

I'm afraid I don't understand what you mean by "plotting like a simulation".

The code I shared adds a new data series to the same plot for each iteration. That data series can be a single point, or a line. It just depends on what data you pass to X and Y.

If you want a new figure for each iteration, this code could do that.

X=0;
Y=cos(X);
while X<2*pi
    X = X+.1;
    Y = cos(X);
    
    figure
    plot(X,Y,'o')
end
