Graph realization problem
WebThe problem uniform sampling a directed graph to a fixed degree sequence is to construct a solution for the digraph realization problem with the additional constraint that such each solution comes with the same probability. This problem was shown to be in FPTAS for regular sequences by Catherine Greenhill The general problem is still unsolved. WebJun 14, 2024 · Fairness is relevant when finding many-to-one matchings between students and colleges, voters and constituencies, and applicants and firms. Here colors may model sociodemographic attributes, party memberships, and qualifications, respectively. We show that finding a fair many-to-one matching is NP-hard even for three colors and maximum …

WebIt turns out that any graph at all can be realized in 3-space because there is enough "room" so that the edges can be chosen in a way so they meet only at the vertices. It is typically hard to determine the minimum number of holes so that the graph can be drawn on a torus with that number of holes.
