<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2>I have a problem when use parallel GA (I used
GADemeGA) with different objectives. I used different objectives for populations
in island model.</FONT></DIV>
<DIV><FONT face=Arial size=2>It means that i assigned each individual objective
for one pupulation. </FONT></DIV>
<DIV><FONT face=Arial size=2>I used GARandomInt for initializing populations to
create arrays of integer numbers between lower-bound and upper-bound
value.</FONT></DIV>
<DIV><FONT face=Arial size=2>I didnot derive a new genome because I just use
1DArray build-in genome for my work.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My problem is: after initializing process there
also some UNDESIRED CHROMOSOMES WITH ALL GENES' VALUES ARE ZERO that
are not in the range of my [lower-bound and upper bound]. Problem about
apprearance of strange, undesired chromosmes is disappeared when
I tested with other GAs such as: simple ga or steadystate (which only deal with
single popolation)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't know where strange come from and how
to eliminate these violated schromosomes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Anyone can help me know what is wrong and how to
solve the problem?</FONT></DIV>
<DIV><FONT face=Arial size=2>your help is highly appreciated. Thank you in
advance.</FONT></DIV>
