Improved Approximation Algorithms for Multidepot Capacitated Vehicle Routing
The Multidepot Capacitated Vehicle Routing Problem (MCVRP) is a well-known variant of the classic Capacitated Vehicle Routing Problem (CVRP), where...

Improved Bounds for the Binary Paint Shop Problem
We improve bounds for the binary paint shop problem posed by Meunier and Neveu [Computing solutions of the paintshop-necklace problem. Comput. Oper....

An Efficient Data Analysis Method for Big Data Using Multiple-Model Linear Regression
This paper introduces a new data analysis method for big data using a newly defined regression model named multiple model linear regression(MMLR),...

Hardness and Approximation for the Star \(\beta \) -Hub Routing Cost Problem in \(\varDelta _\beta \) -Metric Graphs
Minimizing transportation costs through the design of a hub-and-spoke network is a crucial concern in hub location problems (HLP). Within the realm...

Topological Network-Control Games
The paper introduces new combinatorial games, called topological network-control games, played on graphs. These games model the influence of...

Diversity and Freshness-Aware Regret Minimizing Set Queries
Multi-criteria decision-making often involves selecting a small representative set from a database. A recently proposed method is the regret...

A Sub-quadratic Time Algorithm for Computing the Beacon Kernel of Simple Polygons
In 2011, Biro et al. [4] initiated the concept of beacon attraction trajectory motivated by routing messages in sensor network systems. Let P be a...

Linear Time Algorithms for NP-Hard Problems Restricted to GaTEx Graphs
The class of Galled-Tree Explainable (GaTEx) graphs has just recently been discovered as a natural generalization of cographs. Cographs are precisely...

Polynomial Turing Compressions for Some Graph Problems Parameterized by Modular-Width
A polynomial Turing compression (PTC) for a parameterized problem L is a polynomial-time Turing machine that has access to an oracle for a problem...

Shortest Longest-Path Graph Orientations
We consider a graph orientation problem that can be viewed as a generalization of Minimum Graph Coloring. Our problem takes as input an undirected...

k-Median/Means with Outliers Revisited: A Simple Fpt Approximation
We revisit the classical metric k-median/means with outliers in this paper, whose proposal dates back to (Charikar, Khuller, Mount, and Narasimhan...
