Then a crossing reduction step is applied to further improve the readability of the circuit schematics. First we assume that the nodes have already been fixed on a layered hypergraph

orthogonal channels. Efficient channel assignment and routing is essential for throughput optimization of mesh clients. Efficient channel assignment schemes can greatly relieve the interference effect of close-by transmissions; effective routing schemes can alleviate potential congestion on any gateways

configurations using static analysis. rcc detects faults by checking constraints that are based on a high-level correctness specification. rcc detects two broad classes of faults: route validity faults, where routers may learn routes that do not correspond to usable paths, and path visibility faults, where

of a 1-bend visibility graph significantly improves the speed of orthogonal connector routing.

routing we are unaware of any that provide automatic routing for orthogonal hyperedge connectors. We give three algorithms for hyperedge routing in an interactive diagramming editor. The first supports semi-automatic routing in which a route given by the user is improved by local transformations while

Keywords: Approximation Algorithms, parallel computation, CAD, linear time algorithms, minimize congestion. 1 Introduction The problem of Embedding Hypergraphs in a Cycle so a to Minimize Congestion (EHCMC) [3] has applications in design automation (routing nets

In this paper we describe AntHocNet, an algorithm for routing in mobile ad hoc networks. It is a hybrid algorithm, which combines reactive route setup with proactive route probing, maintenance and improvement. The algorithm is based on the Nature-inspired Ant Colony Optimization framework. Paths

The performance of a backbone network is vulnerable to interdomain routing changes that affect how traffic travels to destinations in other Autonomous Systems (ASes). Despite having poor visibility into these routing changes, operators often need to react quickly by tuning the network configuration

restricting the class of polygons to be guarded (orthogonal, etc.), new kinds of guards have been introduced (edgeguards, mobile guards,...) and even watchman routes have been studied. Traditionally, it is assumed that guards can see in any direction. If we imagine cameras, instead of guards, this would imply
