最大有界有根树装箱问题
Maximum Bounded Rooted-Tree Packing Problem
摘要:
给定一个图和一个根,最大有界根树填充(MBRTP)问题的目标是找到K个根树,这些根树覆盖顶点的最大子集,当每个顶点具有有限的出度时。这个问题是由供应不足的系统中的对等流传输覆盖引起的。我们证明了MBRTP问题是NP-完全的。我们提出了两个多项式时间算法,分别计算完全图和树的最优解。
英文摘要:
Given a graph and a root, the Maximum Bounded Rooted-Tree Packing (MBRTP) problem aims at finding K rooted-trees that span the largest subset of vertices, when each vertex has a limited outdegree. This problem is motivated by peer-to-peer streaming overlays in under-provisioned systems. We prove that the MBRTP problem is NP-complete. We present two polynomial-time algorithms that computes an optimal solution on complete graphs and trees respectively.
