    • Finding Large H-Colorable Subgraphs in Hereditary Graph Classes 

      Chudnovsky, Maria; King, Jason; Pilipczuk, Michał; Rzążewski, Paweł; Spirkl, Sophie (Society for Industrial and Applied Mathematics, 2021-10-14)
      We study the Max Partial H-Coloring problem: given a graph G, find the largest induced subgraph of G that admits a homomorphism into H, where H is a fixed pattern graph without loops. Note that when H is a complete graph ...
    • H-colouring Pt-free graphs in subexponential time 

      Groenland, Carla; Okrasa, Karolina; Rzążewski, Paweł; Scott, Alex; Seymour, Paul; Spirkl, Sophie (Elsevier, 2019-08-31)
      A graph is called Pt-free if it does not contain the path on t vertices as an induced subgraph. Let H be a multigraph with the property that any two distinct vertices share at most one common neighbour. We show that the ...
