โฆ Synopsis
This paper considers a stochastic version of bottleneck spanning tree problem in which edge costs are random variables. The problem is to find an optimal spanning tree under the chance constraint with respect to bottleneck (maximum cost) edge of spanning tree. The problem is first transformed into a deterministic equivalent problem. Then its subproblem is introduced and a close relation between these problems is clarified. Finally, based on the relation, an algorithm which finds an optimal spanning tree of the original problem in a polynomial order of its problem size is proposed.

The full-degree spanning tree problem is defined as follows: Given a connected graph G G G = (V V V, E E E), find a spanning tree T T T to maximize the number of vertices whose degree in T T T is the same as in G G G (these are called vertices of "full" degree). This problem is NP-hard. We present a
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
