加权树的连通搜索

Connected searching of weighted trees

Dariusz Dereniowski

摘要:

本文研究了加权树的连通边搜索问题。本文证明了对于边和顶点具有任意权值的有界度树,存在一个多项式时间算法来寻找最优连通搜索策略。对于一般的结点加权树(每条边的权为1),该问题是NP完全的。

英文摘要:

In this paper we consider the problem of connected edge searching of weighted trees. It is shown that there exists a polynomial-time algorithm for finding optimal connected search strategy for bounded degree trees with arbitrary weights on the edges and vertices of the tree. The problem is NP-complete for general node-weighted trees (the weight of each edge is 1).
