3.1 Covering tour problem Coverage aspects have been considered in VRP literature in form of the covering salesman problem (CSP), the covering tour problem (CTP), and the multi-vehicle covering tour problem (m-CTP). These problems deal with the determination of cost-minimal routes such that ev...
Set covering problemDuality gapSet covering problems are well-studied and have many applications. Sometimes the duality gap is significant and the problem is computationally challenging. We dissect the duality gap with the purpose of better understanding its relationship to problem characteristics, such ...
problem) A = F certainly guarantees coverage and is very fast to compute, but might be ineffective by a very large multiplicative factor. Between these extremes, a good ap- proximation algorithm balances a guarantee on effective- ness (for example, in the case of SET COVER, through a proof...
In this paper, we utilize an integer linear programming model (ILP) to formulate the coverage problem, and refer to a well-known problem called the Set Cover problem. Then we propose a heuristic algorithm named as the Set Covering algorithm to solve it. The ultimate object is achieving the ...

We present a -approximation algorithm for the multi-integer set cover problem, for the maximum coverage. This demonstrates that even though the multi-integer set cover problem generalizes the set cover problem, the same approximation ratio holds. In the special case of the facility terminal cover ...

In addition, we analyze the effects of the initial strategies on the gaming result and propose a solution to avoid this effect in order to obtain a better coverage performance. We also extend the optimality of Nash equilibrium in the coverage game to a more general case. Besides that, the ...
Harnessing an alternative greedy argument of Chekuri and Kumar for Maximum Coverage with Group Budget Constraints, on forests of out-trees, we design an algorithm with approximation ratio equal to maximum tree height.Finally, with a reduction from the Planted Dense Subgraph detection problem, we ...
