A parameterized lower bounding method for the open capacitated arc routing problem
Consider an undirected graph with demands scattered over the edges and a homogeneous fleet of vehicles to service the demands. In the open capacitated arc routing problem (OCARP) the objective is to find a set of routes that collectively service all ...

Large Independent Sets on Random d-Regular Graphs with Fixed Degree d
The maximum independent set problem is a classic and fundamental combinatorial challenge, where the objective is to find the largest subset of vertices in a graph such that no two vertices are adjacent.

Two lower bounds for $p$-centered colorings [PDF]
Given a graph $G$ and an integer $p$, a coloring $f : V(G) \to \mathbb{N}$ is \emph{$p$-centered} if for every connected subgraph $H$ of $G$, either $f$ uses more than $p$ colors on $H$ or there is a color that appears exactly once in $H$. The notion of $

Raising NP lower bounds to parallel NP lower bounds [PDF]
This issue's column surveys recent progress in raising NP-hardness lower bounds to parallel NP lower bounds. Complexity theorists will learn that Lewis Carroll (unbeknownst to himself) was a fellow complexity theorist. So that readers specializing in algorithms don't feel left out, let me mention that they are in even better company.

New lower bounds for cap sets, Discrete Analysis 2023:20, 18 pp. One of the best known problems in additive combinatorics, the cap set problem, asks how large a subset of $\mathbb F_3^n$ can be if it contains no non-trivial solutions to the equation $x ...

Almost Periodic Solutions of First-Order Ordinary Differential Equations
Approaches to estimate the number of almost periodic solutions of ordinary differential equations are considered. Conditions that allow determination for both upper and lower bounds for these solutions are found.

DLP in semigroups: Algorithms and lower bounds
The discrete logarithm problem (DLP) in semigroups has attracted some interests and serves as the foundation of many cryptographic schemes. In this work, we study algorithms and lower bounds for DLP in semigroups.

Resonances and lower resolvent bounds [PDF]
We show how the presence of resonances close to the real axis implies exponential lower bounds on the norm of the cut-off resolvent on the real axis.Comment: 13 pages, 3 ...

Solving the Distributed Permutation Flow-Shop Scheduling Problem Using Constrained Programming
The permutation flow-shop scheduling problem is a classical problem in scheduling that aims at identifying the optimal sequence of jobs that should be processed in a number of machines in an effort to minimize makespan or some other performance criterion.

Lower bounds in differential privacy [PDF]
This is a paper about private data analysis, in which a trusted curator holding a confidential database responds to real vector-valued queries. A common approach to ensuring privacy for the database elements is to add appropriately generated random noise
