Heuristic Algorithms for Joint Configuration of the Optical and Electrical Layer in Multi-Hop Wavelength Routing Networks
An efficient and general graph-theoretic model (the Wavelength-Graph (WG)) has been proposed which enables solving the static Routing and Wavelength Assignment (RWA) problems in Mu...

Heuristic algorithms for route-search queries over geographical data
In a geographical route search, given search terms, the goal is to find an effective route that (1) starts at a given location, (2) ends at a given location, and (3) travels via...

Routing multi-class traffic flows in the plane
We study a class of multi-commodity flow problems in geometric domains: For a given planar domain P populated with obstacles (holes) of K ≥ 2 types, compute a set of thick path...

Good triangulations yield good tours
Consider the following heuristic for planar Euclidean instances of the Traveling Salesman Problem (TSP): select a subset of the edges which induces a planar graph, and solve eithe...
