Spanning tree:The spanning tree is a subgraph of the graph. In spanning-tree all the vertex are connected with at least one another vertex and it is having a minimum cost on every edge.Answer and Explanation: Become a member and unlock al...
In this paper by means of an abstract model (the STAR-machine) we describe an associative version of the Gabow algorithm for finding smallest spanning trees with a degree constraint. We have obtained that on an associative parallel processor this algorithm takes the same time as a minimal spanni...
Since the hyperplanes bounding the query region are all vertical, we actually build the partition trees in R~-1, by ignoring the dth coordinate of every point. [] Theorem 9.3. We can find the minimum volume k-point subset of a set of n points in R ~, in time O(kn ~ logd+l n ...

Restricting the subgraph induced on X to be a path (resp. a cycle), the problems Induced-Path, K-Induced-Path, Minimum-Induced-Path, Minimum-K-Induced-Path (resp. the problems Induced-Cycle, K-Induced-Cycle, Minimum-Induced-Cycle, Minimum-K-Induced-Cycle) are defined in the same manner...
A similar problem to the one studied here is that of finding the k minimum weight spanning trees in a graph. Recent algorithms for this problem [21, 22, 25] reduce it to finding the k minimum weight nodes in a heap-ordered tree, defined using the best swap in a sequence of...
If there is no negative cycle, then we can compute the minimum weight paths between all pairs of nodes. Based on this, we can decide if there is a valid alternating path P with w(P)+mod(P)<0 or w(P)+mod(P)=0. □ 3. Proof of the main theorem In this section we prove ...
A spanning tree T of an undirected graph G is a subgraph that includes all of the vertices of G. The importance of spanning trees of various special types has been evident, which are widely used in the analysis of multi-agent systems. The minimum (externally) stable set is another basic ...
(zones 0 and N) each subdivided into a set of level 1 zones, each of which then has two zones (zones A+1 and A+X, zones B and B+1) further split into sets of level 2 zones. A symmetrical hash tree may be easier for firmware/hardware to maintain, although asymmetrical trees can...
