I have the problem of integrating the GA in a part of a program that does GA and other things. Taking ex9 as acase study I have derived a function called getvalue and within this function. This I call this function in my program.as seen at the end this massage. In this sollution I have ignored the argc and argv and this part. The sollution seems to be OK.<o:p></o:p></SPAN></P>
