Hi, Macklem,

I just downloaded ECJ16 and run the parity example:
*(GP) Even 4-Parity* java ec.Evolve -file app/parity/parity.params -p
eval.problem.even=true , and it is OK on my machine.  According to your
description, it seems to be a problem with your parameter file.  There
should NOT be a parameter called "pop.subpop.0.species.pipe.source.0.problem"
unless you are doing some customized design.

The problem is meant to be specified in the way such that, in the parameter
file, e.g., :
there should be a line call "eval.problem=YOUR_PROBLEM_CLASS"(#97 if nothing
is changed)  :
*"eval.problem ="*

Perhaps you can try to mark off all lines start with "
pop.subpop.0.species.pipe.source.0.problem", and check if your problem is
correctly specified.
