Returning to the discussion below after a long break from ECJ.  Both the
suggestions work fine, however ideally I would like to implement multiple
runs in Java (i.e. operating system independent).  Also I would like to
execute the runs sequentially so that I could terminate if a good enough
individual is found.  My problem is I don't see an obvious place to put an
outer loop in ECJ without changing quite a few things. Does anyone know a
simple solution?

Thanks,


Laurie

They'd be equal more or less, but of course they'd all write out to one
big stat file by default.  I've not done it with 50 subpopulations
before -- I always tended to reserve subpopulations for other purposes.
  But I think it'd probably work just fine.
