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 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 out to be exactly the vertex ...

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 ...

The minimum weighted vertex cover (MWVC) problem, an extension of the classical minimum vertex cover (MVC) problem, is an important NP-complete combinatorial optimization problem with a wide range of applications. The objective of this paper is to design an efficient local search algorithm to sol...
