Banzhaf Values for Facts in Query Answering

O Abramovich, D Deutch, N Frost, A Kara… - Proceedings of the ACM …, 2024 - dl.acm.org
Quantifying the contribution of database facts to query answers has been studied as means
of explanation. The Banzhaf value, originally developed in Game Theory, is a natural …

Approximately counting independent sets of a given size in bounded-degree graphs

E Davies, W Perkins - SIAM Journal on Computing, 2023 - SIAM
We determine the computational complexity of approximately counting and sampling
independent sets of a given size in bounded-degree graphs. That is, we identify a critical …

Counting small induced subgraphs satisfying monotone properties

M Roth, J Schmitt, P Wellnitz - SIAM Journal on Computing, 2022 - SIAM
Given a graph property Φ, the problem \#\scIndSub(Φ) asks, on input of a graph G and a
positive integer k, to compute the number IndSub(Φ,k→G) of induced subgraphs of size k in …

Complexity of probabilistic inference in random dichotomous hedonic games

S Cohen, N Agmon - Proceedings of the AAAI Conference on Artificial …, 2023 - ojs.aaai.org
Hedonic games model cooperative games where agents desire to form coalitions, and only
care about the composition of the coalitions of which they are members. Focusing on various …

Computing the number of induced copies of a fixed graph in a bounded degree graph

V Patel, G Regts - Algorithmica, 2019 - Springer
In this paper we show that for any graph H of order m and any graph G of order n and
maximum degree Δ Δ one can compute the number of subsets S of V (G) that induces a …

Stable matchings with restricted preferences: Structure and complexity

CT Cheng, W Rosenbaum - ACM Transactions on Economics and …, 2023 - dl.acm.org
In the stable marriage (SM) problem, there are two sets of agents—traditionally referred to as
men and women—and each agent has a preference list that ranks (a subset of) agents of the …

Counting subgraphs in somewhere dense graphs

M Bressan, L Ann Goldberg, K Meeks, M Roth - SIAM Journal on Computing, 2024 - SIAM
We study the problems of counting copies and induced copies of a small pattern graph in a
large host graph. Recent work fully classified the complexity of those problems according to …

Counting independent sets in cocomparability graphs

M Dyer, H Müller - Information Processing Letters, 2019 - Elsevier
We show that the number of independent sets in cocomparability graphs can be counted in
linear time, as can counting cliques in comparability graphs. By contrast, counting cliques in …

Optimal balanced chain decomposition of partially ordered sets with applications to operating cost minimization in aircraft routing problems

R Vaisman, IB Gertsbakh - Public Transport, 2023 - Springer
We consider the task of constructing a cost-effective daily flight schedule with a minimum
number of required aircrafts and a maximum number of balanced flight routes, namely …

Parameterized Valiant's Classes

M Bläser, C Engels - arXiv preprint arXiv:1907.12287, 2019 - arxiv.org
We define a theory of parameterized algebraic complexity classes in analogy to
parameterized Boolean counting classes. We define the classes VFPT and VW [t], which …
