This study presents the Malatya vertex-cover algorithm, which provides an efficient solution and a robust approach based on the Malatya centrality value algorithm for MVCP. Although MVCP is an NP-complete problem that cannot be solved in polynomial time, the proposed met...
VERTEX-COVER是NP完全的: 相关知识点: 试题来源: 解析 证明: 这里给出一个从3SAT到VERTEX-COVER 的在多项式时间内运算的规约的细节内容,该规约把布尔公式¢映射为一个图G和值k。对于¢中的每个变量x,产生一条连接着两个结点的边。把这个构件中的两个结点标记为。把x赋值为TRUE对应于顶点覆盖选择该边的左...
The vertex cover problem is a classic NP-complete problem for which the best worst-case approximation ratio is roughly 2. In this paper, we use a collection of simple reductions, each of which guarantees an approximation ratio of, to find approximate vertex covers for a large collection of te...

摘要: Starting from the vertex cover problem, this paper obtains a more particular NP-complete problem (comparing with the feedback vertex set problem) and its counterpart in finite automata theory关键词: Theoretical or Mathematical/ finite automata set theory/ vertex cover NP-complete feedback ...
Finding the minimum vertex cover is an NP-complete problem. However, by using some heuristics we can obtain a vertex cover set, which is in the worst case at most twice that of the optimal. Our algorithm provides solutions specifying coverage sensors that can be used as communication sensors ...

The vertex cover problem is a classical NP–complete problem for which the best worstcase approximation ratio is 2–o(1). In this paper, we use a collection of simple graph transformations, each of which guarantees an approximation ratio of 3 2 , to find approximate vertex covers for a lar...

The vertex cover problem is one of the six "basic" NP-complete problems according to Garey and Johnson[ 4 ]. Therefore, the problem cannot be solved in polynomial time unless P \\( { = } \\) NP. However, the NP-completeness of the problem does not obviate the need for solving it ...
