"We have developed a new package-management tool, called Opium, that improves on current tools in two ways: Opium is complete, in that if there is a solution, Opium is guaranteed to find it, and Opium can optimize a user-provided objective function, which could for example state that smaller
packages should be preferred over larger ones. We performed a comparative study of our tool against Debian's apt-get on 600 traces of real-world package installations. We show that Opium runs fast enough to be usable,
and that its completeness and optimality guarantees provide
concrete benefits to end users."

Assuming you meant you have installed none of A,B,X,Y and tried to install A,B, it would say:
Either: {A,X} (i.e. install A and X)
Or: {B,Y} (i.e. install B and Y)
Or: {} (i.e. do nothing) - but I think they probably filter out that option early on
:-P
