A model of a particular mixed electron system is presented. Its formulation gives rise to a combinatorial problem which is shown to be strongly NP-complete. An implicit enumeration algorithm is proposed and some computational experience is reported. A relaxation of the problem is presented such that it is reduced to a flow problem.
