On the existence of stable roommate matchings
WebThe set of envy-free matchings turns out to be a lattice, and the set of stable matchings equals the set of fixed points of a Tarski operator on this lattice. Informally speaking, envy-freeness is a relaxation of stability that allows blocking pairs involving a doctor and an empty position of a hospital.

Webcumvent the negative existence and computational complexity results in matching theory. We characterize the computational complexity of checking the existence and computing individual-based stable matchings for the marriage and roommate settings. One of our key computational results for the stable marriage setting also WebWe compare different preference restrictions that ensure the existence of a stable roommate matching. Some of these restrictions are generalized to allow for indifferences as well as incomplete prefer. ... Kim-Sau, 2000.

Web1 de set. de 2010 · The aim of this paper is to propose a new solution concept for the roommate problem with strict preferences. We introduce maximum irreversible matchings and consider almost stable matchings (Abraham et al., 2006) and maximum stable matchings (Tan 1990, 1991b). These solution concepts are all core consistent. WebStable matchings may fail to exist in the roommate matching problem, both when utility is transferable and when it is not. We show that when utility is transferable, the existence of a stable matching is restored when there is an even number of individuals of indistinguishable characteristics and tastes (types).
WebThe theory of stable matchings has become an important subfield within game theory, as documented by the bookofRoth and Sotomayor (1990). Game theorists are interested in the applications of matching theory in real markets. However, the theory of stable matchings also appeal to combinatorialists and computer scientists.

Definition 2. A matching μ is stable if it is individually rational and if it is not blocked by any pair of agents (X, x)∈ F × M.
