Hi Dirk (and the rest of the list),
I think I have it working; attached is a patch that adds this
functionality to RcppDE. I also came along something which is probably a
bug: The passed environment is never used. In line 75 of DEoptim.R you
just create one. I changed this to

Hi,
ok, that's exactly the file I was looking at right now. The problem is
that my objective function is implemented in C++, and passed as an
external pointer. So in evaluate.h, instead of in the EvalStandard case
I'm in the EvalCompiled case, where the environment is not used. My

I think this may do the trick: demo/env

Dear list,
I'm looking for some advice on a specific problem. Using RcppDE there is
the possibility to give the optimizer directly an external pointer to
the C++ function it will use as the objective function. I found this
mechanism pretty useful as it may speed up things quite a lot (I have a
