Homogeneity Analysis Using Euclidean Minimum Spanning Trees
نویسنده
چکیده
In the usual forms of homogeneity analysis (which are also known as multiple correspondence analysis or MCA) the size of a point set is defined as the size of the star plot of the set. The star plot is the graph defined by connecting all points in the set with their centroid, and the size is the total squared length of the edges. In order to prevent trivial solutions the configuration X is usually centered and normalized such that X X = I . Minimizing total size of the star plots under the normalization constraints amounts to solving a (spare) singular value decomposition problem.

On the Area Requirements of Euclidean Minimum Spanning Trees
In their seminal paper on Euclidean minimum spanning trees [Discrete & Computational Geometry, 1992], Monma and Suri proved that any tree of maximum degree 5 admits a planar embedding as a Euclidean minimum spanning tree. Their algorithm constructs embeddings with exponential area; however, the authors conjectured that c × c area is sometimes required to embed an n-vertex tree of maximum degree...
متن کاملBottleneck Distances and Steiner Trees in the Euclidean d-Space
Some of the most efficient heuristics for the Euclidean Steiner minimal trees in the d-dimensional space, d ≥ 2, use Delaunay tessellations and minimum spanning trees to determine small subsets of geometrically close terminals. Their low-cost Steiner trees are determined and concatenated in a greedy fashion to obtain low cost trees spanning all terminals. The weakness of this approach is that o...

* to be exact, times the weight of a minimum spanning tree (MST). In particular, we present an improved analysis of Chan’s degree-4 MST algorithm [4]. Previous results. Arora [1] and Mitchell [9] presented PTASs for TSP in Euclidean metric, for fixed dimensions. Unfortunately, neither algorithm extends to find degree-3 or degree-4 trees. Recently, Arora and Chang [3] have devised a quasi-polyno...
متن کاملAn Optimal Bound for the MST Algorithm to Compute Energy Efficient Broadcast Trees in Wireless Networks
Computing energy efficient broadcast trees is one of the most prominent operations in wireless networks. For stations embedded in the Euclidean plane, the best analytic result known to date is a 6.33-approximation algorithm based on computing an Euclidean minimum spanning tree. We improve the analysis of this algorithm and show that its approximation ratio is 6, which matches a previously known...
متن کاملConcatenation - Based Greedy Heuristics for the Euclidean
We present a class of O(n log n) heuristics for the Steiner tree problem in the Euclidean plane. These heuristics identify a small number of subsets with few, geometrically close, terminals using minimum spanning trees and other well-known structures from computational geometry: De-launay triangulations, Gabriel graphs, relative neighbourhood graphs, and higher-order Voronoi diagrams. Full Stei...
