A Note on Locating a Set of Points in a Planar Subdivision
SIAM Journal of Computing. Society for Industrial and Applied Mathematics, November, 1979. vol. 8: pp. 542-545 : ill. includes some bibliographical references
In this note the author shows algorithmically that a set of k points can be located in the planar subdivision induced by straight-line planar graph with n vertices in time O(k log k) + O(n) + O(k log n), given a preprocessing time O(n log n)
