MATLAB: Need help generating GA population

chromosomesgapopulation

I am new to GA and there is something that not clear to me. I want to generate a population of k chromosomes with each chromosome length equal to Nt. Each gene in each chromosome is randomly either a '1' or '0'. For every '1' found in a chromosome i want to assign a random number between 1 and 15 for that index position. I need help generating this population.

Try this:

InitPop = randi([0 1], k, Nt);
InitPop(InitPop == 1) = randi([1 15], 1, nnz(InitPop));

This initially creates ‘InitPop’ as a matrix of [0 1] values, tne substitutes the 1 values with integers from 1 to 15.

Apparently, none of the available functionalities of optimalleaforder does the work. So here it is a function that runs through the rows of the tree matrix generated by linkage and produces your output.

function c = binOrd(tree)
      p = size(tree,1);
      c = zeros(1,p+1);
      k = 0;
      recBin(p);
      function recBin(r)
          x = tree(r,1:2)-p-1;
          if x(1)<=0
              c(k+1) = tree(r,1);
              k = k+1;
          else
              recBin(x(1));
          end
          if x(2)<=0
              c(k+1) = tree(r,2);
              k = k+1;
          else
              recBin(x(2));
          end
      end
end

To get your desired rightmost binary ordering, run dendogram with 'Reorder' set as the output of the binOrd function:

tree = linkage(D,'average');
myBinOrder = binOrd(tree);
dendrogram(tree,'Reorder',myBinOrder);

        beat_count=beat_count+1;
        v(end+1) = k % save k value into vector v;
    
    end
