@kash: This is your 276'th question in this forum. And you still get the "homework", "doit4me" and "no_attempt" tags.
Could you please suggest a method, which let you consider the advices in the "how to ask a good question" threads? We have posted the links often enough. You are the user, who has asked the most questions here, but you do not care about the customs and the time of the ones who are answering. This reduces the motivation of others to help you. Does this correspond to your goals?

Walter assuming i have two bits 1056 and 31
1056=10000100000 31=11111;
i am embedding 31 in 1056 so i get 10000111111 which is 1087
now i have to change 6th bit keeping embedded bit constant using GA
after GA i will value closer to 1056 i.e 10000011111 after changing 6th bit which is 1055
please tell how to implement using GA

You already asked that in http://www.mathworks.co.uk/matlabcentral/answers/53255-changing-the-bits-randomly
The solution is completely deterministic, which makes it very difficult for me to figure out why you would want to involve GA.
