We describe an efficient algorithm for maintaining a minimum spanning tree (MST) in a graph subject to a sequence of edge weight modifications. The sequence of minimum spanning trees is computed offline, after the sequence of modifications is known. The algorithm takes time \(O(k \log n)\) for a seq
The degree-constrained spanning tree problem is of high practical importance. Up to now, there are few effective algorithms to solve this problem because of its NP-hard complexity. In this paper, we present a new approach to solve this problem by using genetic algorithms and computational results to
In this paper, we consider the inverse spanning tree problem. Given an undi-0 ลฝ 0 0 . rected graph G s N , A with n nodes, m arcs, an arc cost vector c, and a spanning tree T 0 , the inverse spanning tree problem is to perturb the arc cost vector c to a vector d so that T 0 is a minimum spanning tre
