Hi all,

New to GP and ECJ so please bear with me,

Two questions,

1 Has anyone found a solution which avoids
building a unique class for every variable in
a problem.  Say you have over a thousand
variables, is there a way to define a single
class which returns different variables ???
(I believe this is partly due to how java works)

2 Is there a way to define a function, say
summation or the like, that accepts various
number of children ??? Is there a way to define
a class that takes from zero to x number of children
and is not hard coded in params files but is program
created ???

Thanks for all you help,
