This problem is also known as the group Steiner tree problem or the class Steiner tree problem. Fig. 4 depicts a feasible L-GSTP solution. The L-GSTP is a generalization of the L-GMSTP since the L-GSTP defined on a family of clusters describing a partition of V is a L-GMSTP. This...
The effect of changing various problem parameters on solution time is studied. INFORMS Journal on Computing , ISSN 1091-9856, was published as ORSA Journal on Computing from 1989 to 1995 under ISSN 0899-1499. 展开 关键词: programming: integer cutting plane/facet generation Steiner tree facets ...
Therefore, the Hessian matrix is definite positive, which guarantees that the variance function is strictly convex on the compact set [0,lj]×[0,lk] and the stationary point given by (2) is the minimum, which implies that it is the solution (x1∗,x2∗) of the restricted problem (C...
In this paper, we present a new approach which is spanning tree-based genetic algorithm for bicriteria transportation problem. The transportation problem have the special data structure in solution characterized as a spanning tree. In encoding transportation problem, we introduce one of node encoding ...
Given an undirected network with positive edge costs and a positive integer d > 2, the minimum-degree constrained minimum spanning tree problem is the problem of finding a spanning tree with minimum total cost such that each non-leaf node in the tree has a degree of at least d. This probl...
The prizeヽollecting generalized minimum spanning tree problem consists of finding a minimum cost spanning tree in an undirected graph, considering that the vertices are divided into clusters, that there is a nonnegative cost associated with each edge, that there is a prize to be collected on ...
Most heuristics for the Steiner tree problem in the Euclidean plane perform a series of iterative improvements using the minimum spanning tree as an initial solution. We may therefore characterize them as local search heuristics. In this paper, we first give a survey of existing heuristic approaches...
