最小生成树(Minimum Spanning Tree, MST)是图论中的一个核心概念,特指在一个带权重的无向连通图中,寻找一棵连接所有顶点的树(即无环连通子图),并且这棵树的所有边的权重之和最小。
其核心含义与特性如下:
基础定义与目标
G = (V, E)
,其中 V
是顶点集合,E
是边集合。(u, v) ∈ E
都有一个权重 w(u, v)
(可以是距离、成本、时间等)。T
是 G
的一个子图,它包含 G
的所有顶点(V
),并且是一棵树(即连通且无环)。这意味着 T
恰好有 |V| - 1
条边。关键特性
应用场景
经典求解算法
|V| - 1

最小生成树(Minimum Spanning Tree,简称 MST)是图论中的一个核心概念,指在一个带权无向连通图中,边的权重总和最小的生成树。以下是详细解释:
假设一个图有 4 个顶点,边权重如下:
( A-B: 1 ), ( A-C: 2 ), ( B-C: 3 ), ( B-D: 4 ), ( C-D: 5 )
其 MST 的边为 ( A-B ), ( A-C ), ( B-D ),总权重为 ( 1+2+4=7 )。
通过以上算法和性质,MST 在优化问题中具有广泛的理论和实用价值。
