directionalcrossover.m

good code for matlab by mili , i than you

function ret = DirectionalCrossover(nDes,nP,nDC,X,fX)
%
%	creating children by simple crossover
%  nSc = 1 (only)
%
global xv1 yv1 xv2 yv2
XP1 = X(1,:);
XP2 = X(2,:);
f1 = fX(1);
f2 = fX(2);

r1 = rand(1,1);
for i = 2:2:nDes
	if f1 < f2
   	XC(i) =  XP1(i) + r1*(XP1(i)- XP2(i));
	else
   	XC(i) = XP2(i) + r1*(XP2(i) - XP1(i));
	end
end
%for i = 1:2:nDes-1
 %  if f1 < f2
  %%   if XXC < xv2
    %     XC(i)=XXC;
     % else
      %

    %  end

      %end

   
	%end
%end

%[XP1' XP2']
