Parameterized Complexity of Diameter [PDF]
Algorithmica, 2019 AbstractDiameter—the task of computing the length of a longest shortest path—is a fundamental graph problem. Assuming the Strong Exponential Time Hypothesis, there is no $$O(n^{1.99})$$ O ( n 1.99

On the parameterized complexity of Grid Contraction
Journal of Computer and System Sciences, 2022 For a family of graphs $\mathcal{G}$, the $\mathcal{G}$-\textsc{Contraction} problem takes as an input a graph $G$ and an integer $k$, and the goal is to decide if there exists $F \subseteq E(G)$ of size at most $k$ such that $G/F$ belongs to $\mathcal{G}$. Here, $G/F$ is the graph obtained from $G$ by contracting all the edges in $F$. In this article,

Parameterized Complexity of Broadcasting in Graphs
Theoretical Computer Science, 2023 The task of the broadcast problem is, given a graph G and a source vertex s, to compute the minimum number of rounds required to disseminate a piece of information from s to all vertices in the graph. It is assumed that, at each round, an informed vertex can transmit the information to at most one of its neighbors.

Parameterized Complexity of Gerrymandering
, 2023 In a representative democracy, the electoral process involves partitioning geographical space into districts which each elect a single representative. These representatives craft and vote on legislation, incentivizing political parties to win as many districts as possible (ideally a plurality). Gerrymandering is the process by which district boundaries

Parameterized complexity of reconfiguration of atoms
Algorithmica, 2022 Abstract Our work is motivated by the challenges presented in preparing arrays of atoms for use in quantum simulation. The recently-developed process of loading atoms into traps results in approximately half of the traps being filled. To consolidate the atoms so that they form a dense and regular arrangement, such as all locations in a grid ...

The parameterized space complexity of model-checking bounded variable first-order logic [PDF]
Logical Methods in Computer Science, 2019 The parameterized model-checking problem for a class of first-order sentences (queries) asks to decide whether a given sentence from the class holds true in a given relational structure (database); the parameter is the length of the sentence.

Parameterized learning complexity [PDF]
Proceedings of the sixth annual conference on Computational learning theory - COLT '93, 1993 We describe three applications in computational learning theory of techniques and ideas recently introduced in the study of parameterized computational complexity. (1) Using parameterized problem reducibilities, we show that P -sized DNF (CNF) formulas can be exactly learned in time polynomial in the number of variables by extended equivalence queries ...

On the Parameterized Complexity of Compact Set Packing. [PDF]
Algorithmica, 2023 AbstractThe Set Packing problem is, given a collection of sets $$\mathcal {S}$$ S over a ground set U, to find a maximum collection of sets that are pairwise disjoint. The problem is among the most fundamental NP-hard optimization problems that have been studied extensively in various computational regimes.
