    Plane embeddings of planar graph metrics
    Download  www-math.mit.edu
    Embedding metrics into constant-dimensional geometric spaces, such as the Euclidean plane, is relatively poorly understood. Motivated by applications in visualization, ad-hoc netw...

    Linear-time algorithms for problems on planar graphs with fixed disk dimension
    Download  www.csm.lau.edu.lb
    The disk dimension of a planar graph G is the least number k for which G embeds in the plane minus k open disks, with every vertex on the boundary of some disk. Useful properties ...

    Node-Weighted Steiner Tree and Group Steiner Tree in Planar Graphs
    Download  www-math.mit.edu
    We improve the approximation ratios for two optimization problems in planar graphs. For node-weighted Steiner tree, a classical network-optimization problem, the best achievable ap...
