Constructing minimum-energy broadcast trees in wireless ad hoc networks
In this paper we assume that a multihop wireless network (also called a wireless ad hoc network) consists of nodes whose transmitting powers are finitely adjustable. We consider t...

Efficient minimum spanning tree construction without Delaunay triangulation
Given n points in a plane, a minimum spanning tree is a set of edges which connects all the points and has a minimum total length. A naive approach enumerates edges on all pairs o...

Robust chip-level clock tree synthesis for SOC designs
A key problem that arises in System-on-a-Chip (SOC) designs of today is the Chip-level Clock Tree Synthesis (CCTS). CCTS is done by merging all the clock trees belonging to differ...

A Heuristic Method for Generating 2D CSG Trees from Bitmaps
This paper presents a method for generating compact and effective constructive-solid-geometry (CSG) object representations from 2D bitmap representations. The method consists of t...

An Improved LP-based Approximation for Steiner Tree
The Steiner tree problem is one of the most fundamental ÆÈ-hard problems: given a weighted undirected graph and a subset of terminal nodes, find a minimum weight tree spanning ...
