<P>Unfortunately, it is not a quite simple problem. Since bestIndividual is of type GaGenome& you could not access its value directly. I solved this problem by first printing the bestIndividual value to a file, then reading its value from that file and assigning it to a new variable.</P>
<P>One way is to use file stream operators as follows:</P>
<P>ofstream fout;</P>
<P>fout.open("bestInd.txt", ios::in);</P>
<P>if (!fout.fail()){</P>
<P>fout << ga.statistics().bestIndividual() ;</P>
<P>fout.close();</P>
<P>}</P>
<P>ifstream fin;</P>
<P>fin.open("bestInd.txt", ios::out);</P>
<P>if (!fin.fail()){</P>
<P>float bestInd,</P>
<P>fin >> bestInd; // read the value from file and write it to bestInd</P>
<P>fin.close();</P>
<P>}</P>
<P>Hope this helps ...</P>
