    Independent Roman Domination: The Complexity and Linear-Time Algorithm for Trees by Zhixing Duan, Huiqin Jiang, Xinyue Liu, Pu Wu, Zehui Shao

    Published 2022-02-01
    “…In this paper, we prove that the decision problem of minimum IRDF is <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>N</mi><mi>P</mi></mrow></semantics></math></inline-formula>-complete for chordal bipartite graphs. Then, we research the difference in complexity between the decision problem of RDF and IRDF. …”

    A reverse Sidorenko inequality by Sah, Ashwin, Sawhney, Mehtaab, Stoner, David, Zhao, Yufei

    Published 2021
    “…For 2-spin Ising models, our results give a complete characterization of extremal graphs: complete bipartite graphs maximize the partition function of 2-spin antiferromagnetic models and cliques maximize the partition function of ferromagnetic models. …”

    Method of information technology for structure analysis of urban network fire-rescue units by Svitlana Danshyna, Artem Nechausov

    Published 2023-12-01
    “…The study of the classical location problem and its adaptation to real problems arising from the analysis of the urban network of fire-rescue units made it possible to represent it as a set of independent complete bipartite graphs. To search the location of network nodes while solving an adapted problem, an IT method is developed, which, based on the p-median model, combines the author’s methodology for studying information processes and methods of geospatial analysis. …”

    Bridging Theory and Practice in Parallel Clustering by Shi, Jessica

    Published 2023
    “…We address bi-core decomposition and butterfly peeling, which are specialized algorithms for bipartite graphs, and we study k-clique peeling and nucleus decomposition, which generalize classic decomposition algorithms to higher order structures. …”

    Total Roman {3}-Domination: The Complexity and Linear-Time Algorithm for Trees by Xinyue Liu, Huiqin Jiang, Pu Wu, Zehui Shao

    Published 2021-02-01
    “…In this paper, we show that the total Roman {3}-domination problem is NP-complete for planar graphs and chordal bipartite graphs. Finally, we present a linear-time algorithm to compute the value of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>γ</mi><mrow><mi>t</mi><mo stretchy="false">{</mo><mi>R</mi><mn>3</mn><mo stretchy="false">}</mo></mrow></msub></semantics></math></inline-formula> for trees.…”
