The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Complexity and Approximation of the Rectilinear Steiner Tree ProblemMussafi, Noor Saif Muhammad 05 August 2009 (has links)
Given a finite set K of terminals in the plane. A
rectilinear Steiner minimum tree for K (RST) is
a tree which interconnects among these terminals
using only horizontal and vertical lines of shortest
possible length containing Steiner point. We show the
complexity of RST i.e. belongs to NP-complete.
Moreover we present an approximative method of
determining the solution of RST problem proposed by Sanjeev Arora
in 1996, Arora's Approximation Scheme. This algorithm
has time complexity polynomial in the number of
terminals for a fixed performance ratio 1 + Epsilon.
