Computing the , × , Shortest Paths Efficiently traveling salesperson problem (TSP) and the vehicle routing problem (VRP). This paper proposes new algorithms that compute the set of shortest paths efficiently by using the A* algorithm. The efficiency and properties of these algorithms are examined by using the results of experiments on an actual road network.

Obstacle-Avoiding Euclidean Steiner Trees in the Plane: An Exact Algorithm uses a two-phase framework — based on the generation and concatenation of full Steiner trees — previously shown to be very successful for the obstacle-free case. Computational results for moderate size problem instances are given; instances with up to 150 terminals have been solved to optimality within a few hours of CPU-time.

Fatma Abdelkhalek,Marianna Bollaiques and the choice of geometric representation affect performance. In particular we investigate the cost of exact computation. We use C++ as the implementation language. Our experiments are largely based on Cgal.
