PTAS for Euclidean and rectilinear Steiner trees
Derives the Steiner ratio for k-restricted Steiner trees in graphs, i.e. those in which no full tree contains more than k terminals.
A full-set decomposition algorithm and other results for rectilinear Steiner trees of terminals from a small integer grid
An O(n 3^n) algorithm for computing optimal rectilinear Steiner trees
An O(n^2 2.62^n) algorithm for computing optimal rectilinear Steiner trees
Proves an analogue of Hanan's theorem for rectilinear Steiner trees in the presence of obstacles, and some related results
A full-set decomposition algorithm and other results for rectilinear Steiner trees of terminals from a small integer grid
An O(n 3^n) algorithm and an O(n^2 2.62^n) algorithm for computing optimal rectilinear Steiner trees
An exact algorithm for Euclidean Steiner trees that minimize the length of the longest edge, and the value of the corresponding version of the Steiner ratio
Proves that the Euclidean Steiner tree problem is NP-hard
