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 each, covering a set of points in a geographic area.

Genetic algorithm efficiency improvement in the course of set cover problem solution
Introduction. Practical tasks (location of service points, creation of microcircuits, scheduling, etc.) often require an exact or approximate to exact solution at a large dimension.

Incremental Updating Algorithm for Approximation Sets on Semi-Monolayer Cover Rough Sets [PDF]
A one-to-one mapping relationship exists between the semi-monolayer cover rough sets and the set-valued information system.When an object set in a set-valued information system is dynamically added or removed, the information unit that corresponds to the

Exact and greedy algorithms of allocating experts to maximum set of programmer teams
The allocation of experts to programmer teams, which meet constraints on professional competences related to programming technologies, languages and tools an IT project specifies is a hard combinatorial problem.

Towards Tight Bounds for the Streaming Set Cover Problem [PDF]
We consider the classic Set Cover problem in the data stream model. For $n$ elements and $m$ sets ($m\geq n$) we give a $O(1/\delta)$-pass algorithm with a strongly sub-linear $\tilde{O}(mn^{\delta})$ space and logarithmic approximation factor.

Greedy Game Algorithms for Solving SET
Coverage is a fundamental problem in heterogeneous wireless sensor networks (HWSNs). Lifetime of the HWSNs is another important problem in this area. The K-Cover problem can solve both the coverage and lifetime issues.

Vertex Cover Gets Faster and Harder on Low Degree Graphs [PDF]
The problem of finding an optimal vertex cover in a graph is a classic NP-complete problem, and is a special case of the hitting set question. On the other hand, the hitting set problem, when asked in the context of induced geometric objects, often turns

The Minimum Weighted Connected Vertex Cover problem (MWCVC) is to find a subset $F\subset V(G)$ with minimum weight in a node-weighted graph $G$ , such that when removing the set $F$ , the inducing graph of remaining vertices holds no edges, and the ...
