ECJ, A Java-based Evolutionary Computation Research System. ECJ is a research EC system written in Java. It was designed to be highly flexible, with nearly all classes (and all of their settings) dynamically determined at runtime by a user-provided parameter file. All structures in the system are arranged to be easily modifiable. Even so, the system was designed with an eye toward efficiency. ECJ is developed at George Mason University's ECLab Evolutionary Computation Laboratory. The software has nothing to do with its initials' namesake, Evolutionary Computation Journal. ECJ's sister project is MASON, a multi-agent simulation system which dovetails with ECJ nicely.

The newest version!

Ellis, Gilligans, Coney, Fantasy, Rhode, Survivor, Temptation,
and Treasure Island.  Survivor Island will be the server.

To run this example, launch eight processes, each with
the appropriate .params file for that island.  

If you're running them on the same machines, you can
simply do:

java ec.Evolve -file survivor.params

java ec.Evolve -file ellis.params

java ec.Evolve -file gilligans.params

java ec.Evolve -file coney.params

java ec.Evolve -file fantasy.params

java ec.Evolve -file rhode.params

java ec.Evolve -file temptation.params

java ec.Evolve -file treasure.params


If you're running the processes on different machines,  
you'll need to modify the server address
so the machines know where Survivor Island (the server) is located:

java ec.Evolve -file survivor.params 

java ec.Evolve -file ellis.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file gilligans.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file coney.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file fantasy.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file rhode.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file temptation.params \
    -p exch.server-addr=address.of.survivor.com

java ec.Evolve -file treasure.params \
    -p exch.server-addr=address.of.survivor.com


The parameter files have been set up to define different
socket ports for each client; though this is only necessary
if they're running on the same computer.
