Fine-Grained Complexity of Earth Mover's Distance under Translation

Karl Bringmann, Frank Staals, Karol Węgrzycki +1

The Earth Mover's Distance is a popular similarity measure in several branches of computer science. It measures the minimum total edge length of a perfect matching between two poin…

Improving Lagarias-Odlyzko Algorithm For Average-Case Subset Sum: Modular Arithmetic Approach

Antoine Joux, Karol Węgrzycki

Lagarias and Odlyzko (J.~ACM~1985) proposed a polynomial time algorithm for solving ``\emph{almost all}'' instances of the Subset Sum problem with integers of size $Ω(Γ_{\tex…

Sensitivity, Proximity and FPT Algorithms for Exact Matroid Problems

Friedrich Eisenbrand, Lars Rohwedder, Karol Węgrzycki

We consider the problem of finding a basis of a matroid with weight exactly equal to a given target. Here weights can be discrete values from or more generally…

Parameterized Algorithms on Integer Sets with Small Doubling: Integer Programming, Subset Sum and k-SUM

Tim Randolph, Karol Węgrzycki

We study the parameterized complexity of algorithmic problems whose input is an integer set in terms of the doubling constant , a fundamental measure of addit…

Polynomial Time Algorithms for Integer Programming and Unbounded Subset Sum in the Total Regime

Divesh Aggarwal, Antoine Joux, Miklos Santha +1

The Unbounded Subset Sum (USS) problem is an NP-hard computational problem where the goal is to decide whether there exist non-negative integers such that $x_1 a…
