Function DEoptim in package DEoptim for differential evolution defines an
optional parameter fnMap:
fnMap
"an optional function that will be run after each population is created, but
before the population is passed to the objective function. This allows the user
to impose integer/cardinality constriants."
Unfortunately, there is no further documentation decribing the kind of
parameters being passed to this function on invocation or the structure of the
return value expected. I would very much appreciate it if somebody familiar
with this package could provide an example illustrating how this interface is
meant to be used to enforce cardinality constraints.
Thanks,
David
