Beyond Exact Fairness: Envy-Free Incomplete Connected Fair Division

Ajaykrishnan E S, Daniel Lokshtanov

We study the problem of Envy-Free Incomplete Connected Fair Division, where exactly p vertices of an undirected graph must be allocated to agents such that each agent receives a co…

Induced minors and subpolynomial treewidth

Maria Chudnovsky, Julien Codsi, David Fischer +1

Given a family of graphs, we say that a graph is -induced-minor-free if no induced minor of is isomorphic to a member of , We denote…

A Quasi-Polynomial Time Algorithm for 3-Coloring Circle Graphs

Ajaykrishnan E S, Robert Ganian, Daniel Lokshtanov +1

A graph is a circle graph if it is an intersection graph of chords of a unit circle. We give an algorithm that takes as input an vertex circle graph , runs in time at mo…

(Treewidth, Clique)-Boundedness and Poly-logarithmic Tree-Independence

Maria Chudnovsky, Ajaykrishnan E S, Daniel Lokshtanov

An independent set in a graph is a set of pairwise non-adjacent vertices. A tree decomposition of is a pair where is a tree and …

Sampling Unlabeled Chordal Graphs in Expected Polynomial Time

Úrsula Hébert-Johnson, Daniel Lokshtanov

We design an algorithm that generates an -vertex unlabeled chordal graph uniformly at random in expected polynomial time. Along the way, we develop the following two results: (1…
