最小权Steiner树(MST)是一个重要的网络组合优化问题,在许多领域有着广泛的应用。在这里,我们讨论了一种通用的技术,将强加的全球连接约束转化为许多本地的,可以与腔方程技术进行分析。这种方法导致一个新的优化算法MST,并允许我们分析的统计力学性质的MST的随机图的各种类型。
The minimum weight Steiner tree (MST) is an important combinatorial optimization problem over networks that has applications in a wide range of fields. Here we discuss a general technique to translate the imposed global connectivity constrain into many local ones that can be analyzed with cavity equation techniques. This approach leads to a new optimization algorithm for MST and allows us to analyze the statistical mechanics properties of MST on random graphs of various types.
