A Simple and Quick Approximation Algorithm for Traveling Salesman Problem in the Planem runs in . log .) time with . space, and is simple enough to easily implement on resource restricted machines. It constructs a tour essentially by axis-sorts of the points and takes a kind of the ‘fixed dissection strategy,’ though it neither tries to find best tours in subregions nor optimizes the

On Approximating Minimum Vertex Cover for Graphs with Perfect Matchingtex Cover problem on general graphs. Approximation algorithms for VC-PM are developed, which induce improvements over previously known algorithms on sparse graphs. For example, for graphs of average degree 5, the approximation ratio of our algorithm is 1.414, compared with the previously best ratio 1.615 by Halldórsson and Radhakrishnan.

An Approximate Algorithm for the Weighted Hamiltonian Path Completion Problem on a Tree path completion problem on a tree is still NP-hard. Then it is shown that this problem will unlikely have any fully polynomial-time approximation scheme (FPTAS) unless NP=P. When the given tree is a .-tree, we give an approximation algorithm with performance ratio 1.5.

Der Luftverkehr und seine Subventionents on a surface is closely related to the way the Voronoi diagram of the sample points approaches the medial axis of the surface when the sampling density increases. Elucidating the question of approximating the medial axis of a surface leads to new theoretical results in surface reconstruction and new algorithms with provable guarantees.

Die Machtbegriffe im Vergleich, This paper gives theoretical support for using 4-opt-type neighborhood operations by discussing the connectivity of its solution space and the size of the neighborhood. Another interesting point in our model is a special case of the NSP corresponds to the bipartite transportation problem, and our result also applies to it.
