I have a set of random points plotted. I want to create a random walk between all of these plotted points so they are all visited once and only once. Then i will want to repeat many more random walks to find the best solution.

I am struggling with the logic needed to plot lines between my points and make sure they are only visited once. So any help with that would be appreciated, the rest i can work out.

Hi.

plot([x1 x2],[y1,y2])

For all lines:

xCor = rand(1,10) yCor = rand(1,10) Cor = [xCor; yCor] subplot(1,1,1); plot(xCor,yCor,'r.','MarkerSize',20) c = randperm(10,10) x1 = Cor(1,c(1:9)) y1 = Cor(2,c(1:9)) x2 = Cor(1,c(2:10)) y2 = Cor(2,c(2:10)) hold on; plot([x1;x2],[y1;y2])

I have this so far to try and get my plotting correct.

I create my Coordinate set Cor and plot the individual x and y points. I then create a random permutation so that i can select random Columns from Cor. When the numbers are printed out for x1, y1 etc . . they all match with the numbers in Cor and the numbers that were plotted but the plotted line does not relate to any points on my figure . . .despite having the same co ordinates.
