Tree-independence number of -free graphs with no large bicliques

Václav Blažej, J. Pascal Gollin, Tomáš Hons +5

The tree-independence number of a graph is the minimum, over all tree-decompositions of the graph, of the maximum size of an independent set contained in a bag. Graph classes of bo…

Tree-independence number VII. Excluding a star

Maria Chudnovsky, Jadwiga Czyżewska, Marcin Pilipczuk +1

We prove that for every fixed integer and every planar graph , the class of -induced-minor-free and -induced-subgraph-free graphs has polylogarithmic tree-indepe…

Maximum Partial List H-Coloring on P_5-free graphs in polynomial time

Daniel Lokshtanov, Paweł Rzążewski, Saket Saurabh +2

In this article we show that Maximum Partial List H-Coloring is polynomial-time solvable on P_5-free graphs for every fixed graph H. In particular, this implies that Maximum k-Colo…

Odd Cycle Transversal on -free Graphs in Polynomial Time

Akanksha Agrawal, Paloma T. Lima, Daniel Lokshtanov +3

An independent set in a graph G is a set of pairwise non-adjacent vertices. A graph is bipartite if its vertex set can be partitioned into two independent sets. In the Odd Cycl…

Max Weight Independent Set in sparse graphs with no long claws

Tara Abrishami, Maria Chudnovsky, Cemil Dibek +2

We revisit the recent polynomial-time algorithm for the MAX WEIGHT INDEPENDENT SET (MWIS) problem in bounded-degree graphs that do not contain a fixed graph whose every component i…

Sparse induced subgraphs in P_6-free graphs

Maria Chudnovsky, Rose McCarty, Marcin Pilipczuk +2

We prove that a number of computational problems that ask for the largest sparse induced subgraph satisfying some property definable in CMSO2 logic, most notably Feedback Vertex Se…
