Re: Anyone can introduce GA resource?

The coding of GA's is actually amazingly simple

Quoting my wife ==> >>easy for you to say !!<<


and often the theories speak
directly into the code (mainly because they revolve around the manipulation
of bitvectors instead of abstract data). In fact I don't think your
criticism is justified since what you say is true for any scientific field,

but don't you think in particular the optimization methods of today.


there are so many now and GA proports to be one of the best and I think each author has their own twists and tunings



whether it is maths or physics; the implementation itself is a different
job entirely and is considered the manufactural process which is, in
essence, easy. That said there are many books on GA that focus on, for
instanc,e game programming (be it entertaining or economic games), or
simulation, that carry source code directly into C or Java.
There are also free GA and GP API's in Java that basically teach you the
whole process by using them.


the problem I have is that there seems to be only about one fortran interpretation on the web and it appears somewhat out of date and looks anyways not so easy to use.


additionally and importantly I am look for code that can easily do 100 to 1000 variables. I don't think I can find same in Fortran.

If you have any suggestions I would be grateful

(hey I see you are from no I am 1/4 no and 3/4 se. Seems some no tells me in the past that 1/4 more than makes up for the 3/4 !!!!!
