You write your individuals file. You need naming definition like
"simulation"_+"generation"_id.
And you just write your customized individual/population writing method. In
java there are quite
standard ways to write file so kind of don't understand question.

Aha jou as I also. Just call evolve function between those players you want
to compare and save result for some file.
Traditionally if you really want to see are you individuals progressing in
co-evolution you should have external fitness measuring
function which is not part of evolutive prosess.
