Island Model

Hi

I’m interested in using JGAP in a test harness I’m developing.  But before I do, could I check a few things with you to see if JGAP will support my requirements:

1)       I need to implement an Island model (which I’ve never done before, so the easier the better), I notice in one of the source files, this is added as a TODO.  Has it been implemented else where, or is is very easy to implement in what is already there with the distribution model in JGAP (I notice population merging seems to be available).

2)       I need to run an external command, and then parse a text file output by this command to evaluate my fitness.  At the moment I’m just using a threadpool of runtime.exec()s to do this, will JGAP support this (I suppose there should be no reason why it shouldn’t) or even support the runtime.exec()s and the threads being handled by JGAP itself under it’s server/client model?

If these aren’t possible, or this would be easier using another Java Genetic Algorithm library, could you possibly suggest one also?  I am also looking at ECJ (and wishing GAUL was available for Java), if these help?

Thank you for any help and suggestions you can give.
