The concept of stable assignment comes from a classical assignment problem called the Stable Marriage Assignment. Suppose that there are two disjoint sets, one consists of men and the other of women. Each member of a set ranks the members of the other set in order of preference. Matching persons between two sets is a one-to-one relation. If there does not exist a random pair both preferring each other to their assigned partner, the assignment is said to be stable. In a recent paper. Huang and Chan generalized the above one-to-one type assignment problem to a multi-function assignment problem and proposed an algorithm for finding stable assignments for both problems. In this paper, we present a couterexample for which the assignment obtained by that algorithm is not stable.
