A survey on approximation in parameterized complexity: Hardness and algorithms

AE Feldmann, E Lee, P Manurangsi - Algorithms, 2020 - mdpi.com
Parameterization and approximation are two popular ways of coping with NP-hard
problems. More recently, the two have also been combined to derive many interesting …

Determinantal sieving

E Eiben, T Koana, M Wahlström - Proceedings of the 2024 Annual ACM-SIAM …, 2024 - SIAM
We introduce a new, remarkably powerful tool to the toolbox of algebraic FPT algorithms,
determinantal sieving. Given a polynomial P (x 1,…, xn) over a field 𝔽 of characteristic 2, on …

Waring rank, parameterized and exact algorithms

The complexity of pattern counting in directed graphs, parameterised by the outdegree

M Bressan, M Lanzinger, M Roth - Proceedings of the 55th Annual ACM …, 2023 - dl.acm.org
We study the fixed-parameter tractability of the following fundamental problem: given two
directed graphs H→ and G→, count the number of copies of H→ in G→. The standard …

Cache persistence analysis: Finally exact

G Stock, S Hahn, J Reineke - 2019 IEEE Real-Time Systems …, 2019 - ieeexplore.ieee.org
Cache persistence analysis is an important part of worst-case execution time (WCET)
analysis. It has been extensively studied in the past twenty years. Despite these efforts, all …

Parameterized (modular) counting and Cayley graph expanders

We study the problem $\#\mathrm {EdgeSub}(\Phi) $ of counting $ k $-edge subgraphs
satisfying a given graph property $\Phi $ in a large host graph $ G $. Building upon the …

Fast exact algorithms using Hadamard product of polynomials

V Arvind, A Chatterjee, R Datta, P Mukhopadhyay - Algorithmica, 2022 - Springer
Let C be an arithmetic circuit of size s, given as input that computes a polynomial f ∈ F x_1,
x_2, ..., x_n f∈ F x 1, x 2,…, xn, where FF is a finite field or the field of rationals. Using the …

Parameterized applications of symbolic differentiation of (totally) multilinear polynomials

C Brand, K Pratt - 48th International Colloquium on Automata …, 2021 - drops.dagstuhl.de

Parameterized sensitivity oracles and dynamic algorithms using exterior algebras

J Alman, D Hirsch - arXiv preprint arXiv:2204.10819, 2022 - arxiv.org
We design the first efficient sensitivity oracles and dynamic algorithms for a variety of
