BTW if you've been wondering why ECJ hasn't had any releases lately it's becasue we've been making significant non-backward-compatible changes in a separate repository. We will very soon be releasing a new version of ECJ we've had under wraps. It has:

- Some non-backward-compatible rearchitecting
- subpopulation and individual arrays are now ArrayLists
- changes to how/when evaluations and generations are computed
- custom parameters passed into breeding pipelines
- parent statistics for children, more later (like birthdays)
- some other stuff
- Several new selection and breeding operators
- A dedicated "single state" package to make hill-climbing
and simualted annealing methods more efficient
- A package for partition-based divide-and-conquer metaheuristics methods
(DOVS)
- A NEAT package
- A testing facility (not included yet)

This is our first step in ECJ's three-year enhancement program. We'll be ramping up big-time after GECCO.
