Arborescences, Colorful Forests, and Popularity Telikepalli Kavitha, Kazuhisa Makino, Ildikó Schlotter, and Yu Yokoi Abstract Our input is a directed, rooted graph G = (V ∪ {r}, E) where each vertex in V has a partial order preference over its incoming edges. The preferences of a vertex extend naturally to preferences over arborescences rooted at r. We seek a popular arborescence in G, i.e., one for which there is no “more popular” arborescence. […]

Computational complexity of necessary envy-freeness Haris Aziz, Ildikó Schlotter, Toby Walsh Highlights Envy-free allocation of indivisible items to a few agents is computationally hard. Finding a necessarily envy-free allocation is NP-hard already for 3 agents. For any n ≥ 3 , finding a necessarily envy-free allocation for agents is NP-hard. Abstract We consider the fundamental […]
