The Minimization of Public Facilities With Enhanced Genetic Algorithms Using War Elimination

open access: yesIEEE Access, 2019
In this paper, we focus on the problem of minimizing a network of state facilities that provide essential public services (schools, offices, and hospitals).

Set It and Forget It: Approximating the Set Once Strip Cover Problem [PDF]

open access: yes, 2012
We consider the Set Once Strip Cover problem, in which n wireless sensors are deployed over a one-dimensional region. Each sensor has a fixed battery that drains in inverse proportion to a radius that can be set just once, but activated at any time.

Replica Placement on Bounded Treewidth Graphs

open access: yes, 2017
We consider the replica placement problem: given a graph with clients and nodes, place replicas on a minimum set of nodes to serve all the clients; each client is associated with a request and maximum distance that it can travel to get served and there ...

An indirect genetic algorithm for set covering problems [PDF]

open access: yesJournal of the Operational Research Society, 2002
This paper presents a new type of genetic algorithm for the set covering problem. It differs from previous evolutionary approaches first because it is an indirect algorithm, i.e. the actual solutions are found by an external decoder function. The genetic algorithm itself provides this decoder with permutations of the solution variables and other ...

Covering Pairs in Directed Acyclic Graphs

open access: yes, 2013
The Minimum Path Cover problem on directed acyclic graphs (DAGs) is a classical problem that provides a clear and simple mathematical formulation for several applications in different areas and that has an efficient algorithmic solution.

Weighted geometric set cover problems revisited

open access: yesJournal of Computational Geometry, 2012
We study several set cover problems in low dimensional geometric settings. Specifically, we describe a PTAS for the problem of computing a minimum cover of given points by a set of weighted fat objects. Here, we allow the objects to expand by some prespecified δ-fraction of their diameter.

The complete vertex p-center problem

open access: yesEURO Journal on Computational Optimization, 2020
The vertex p-center problem consists of locating p facilities among a set of M potential sites such that the maximum distance from any demand to its closest located facility is minimized.

Calibrations for minimal networks in a covering space setting

open access: yes, 2019
In this paper we define a notion of calibration for an equivalent approach to the classical Steiner problem in a covering space setting and we give some explicit examples. Moreover we introduce the notion of calibration in families: the idea is to divide
