Hi,



    I need to put a small GUI on top of an ECJ application. The GUI would

give the user control over a couple of ECJ parameters, like population size,

number of generations, mutation rate, etc. I would still like to store the

rest of my parameters in a parameter file. The GUI should also provide 4

buttons: Start, Stop, Pause & Resume.

    For the first part, concerning parameters, what's the easiest way to

achieve it other than generating a parameter file from the code and then

calling Evolve.main?

    For the second part, can I use checkpoints to implement it, given the

fact that I do not know when the user will press Pause? Or is there another

way to do it?



    Thanks in advance,

    Elena
