Uniform Random Covering Problems [PDF]

open access: yesInternational Mathematics Research Notices, 2021
Abstract Motivated by the random covering problem and the study of Dirichlet uniform approximable numbers, we investigate the uniform random covering problem. Precisely, consider an i.i.d. sequence $\omega =(\omega _n)_{n\geq 1}$ uniformly distributed on the unit circle $\mathbb{T}$ and a sequence $(r_n)_{n\geq 1}$ of positive real ...

Covering Graphs: The Covering Problem Solved

open access: yesJournal of Combinatorial Theory, Series A, 1998
Let \(H\) be a fixed graph with \(h\) edges such that the gcd of all degrees of \(H\) is \(d\). The authors prove that for all \(n>n_0(H)\), where \(n_0(H)\) is enormous, the \(H\)-covering number of \(K_n\) is \(\left \lceil {dn\over 2h}\left \lceil {n-1 \over d} \right\rceil \right \rceil\) except for \(d\equiv 0\pmod 2\), \(n\equiv 1 \pmod d\), \(n ...

Frobenius problem and the covering radius of a lattice [PDF]

open access: yes, 2006
Let $N \geq2$ and let $1 < a_1 < ... < a_N$ be relatively prime integers. Frobenius number of this $N$-tuple is defined to be the largest positive integer that cannot be expressed as $\sum_{i=1}^N a_i x_i$ where $x_1,...,x_N$ are non-negative integers ...

Hybrid Set Covering and Dynamic Modular Covering Location Problem: Application to an Emergency Humanitarian Logistics Problem

open access: yesApplied Sciences, 2020
This paper presents an extension of the covering location problem as a hybrid covering model that utilizes the set covering and maximal covering location problems. The developed model is a multi-period model that considers strategic and tactical planning

Two meta-heuristics for solving the multi-vehicle multi-covering tour problem with a constraint on the number of vertices [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
In this work we deal with a generalized variant of the multi-vehicle covering tour problem (m-CTP). The m-CTP consists of minimizing the total routing cost and satisfying the entire demand of all customers, without the restriction of visiting them all ...

The multimode covering location problem [PDF]

open access: yes, 2016
In this paper we introduce the Multimode Covering Location Problem. This is a generalization of the Maximal Covering Location Problem that consists in locating a given number of facilities of different types with a limitation on the number of facilities ...

A Surprisal-Based Greedy Heuristic for the Set Covering Problem

open access: yesAlgorithms, 2023
In this paper we exploit concepts from Information Theory to improve the classical Chvatal greedy algorithm for the set covering problem. In particular, we develop a new greedy procedure, called Surprisal-Based Greedy Heuristic (SBH), incorporating the ...

Hub Covering Location Problem Considering Queuing and Capacity Constraints [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2018
In this paper, a hub covering location problem is considered. Hubs, which are the most congested part of a network, are modeled as M/M/C queuing system and located in placeswhere the entrance flows are more than a predetermined value.A fuzzy constraint ...
