    • Approximately Coloring Graphs Without Long Induced Paths 

      Chudnovsky, Maria; Schaudt, Oliver; Spirkl, Sophie; stein, maya; Zhong, Mingxian (Springer Nature, 2017)
      It is an open problem whether the 3-coloring problem can be solved in polynomial time in the class of graphs that do not contain an induced path on t vertices, for fixed t. We propose an algorithm that, given a 3-colorable ...
    • Complexity of Ck-Coloring in Hereditary Classes of Graphs 

      Chudnovsky, Maria; Huang, Shenwei; Rzążewski, Paweł; Spirkl, Sophie; Zhong, Mingxian (Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik, 2019)
      For a graph F, a graph G is F-free if it does not contain an induced subgraph isomorphic to F. For two graphs G and H, an H-coloring of G is a mapping f : V (G) --> V (H) such that for every edge uv E(G) it holds that ...
