The Angular Set Covering Problem
We present an innovative extension of the Set Covering Problem, transitioning from a traditional radial covering to an angular covering structure. The decisions are based on locating the facilities and identifying the directional servers installed in ...

Application of the Artificial Bee Colony Algorithm for Solving the Set Covering Problem [PDF]
The set covering problem is a formal model for many practical optimization problems. In the set covering problem the goal is to choose a subset of the columns of minimal cost that covers every row.

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

A Surprisal-Based Greedy Heuristic for the Set Covering Problem
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 ...

The online set cover problem [PDF]
Let $X=\{1,2,\ldots,n\}$ be a ground set of $n$ elements, and let ${\cal S}$ be a family of subsets of $X$, $|{\cal S}|=m$, with a positive cost $c_S$ associated with each $S\in{\cal S}$. Consider the following online version of the set cover problem, described as a game between an algorithm and an adversary.

Ant-Set: A Subset-Oriented Ant Colony Optimization Algorithm for the Set Covering Problem [PDF]
This paper proposes an algorithm for the set covering problem based on the metaheuristic Ant Colony Optimization (ACO) called Ant-Set, which uses a lineoriented approach and a novelty pheromone manipulation based on the connections between components of ...
