最小生成樹(Minimum Spanning Tree, MST)是圖論中的一個核心概念,特指在一個帶權重的無向連通圖中,尋找一棵連接所有頂點的樹(即無環連通子圖),并且這棵樹的所有邊的權重之和最小。
其核心含義與特性如下:
基礎定義與目标
G = (V, E)
,其中 V
是頂點集合,E
是邊集合。(u, v) ∈ E
都有一個權重 w(u, v)
(可以是距離、成本、時間等)。T
是 G
的一個子圖,它包含 G
的所有頂點(V
),并且是一棵樹(即連通且無環)。這意味着 T
恰好有 |V| - 1
條邊。關鍵特性
應用場景
經典求解算法

最小生成樹(Minimum Spanning Tree,簡稱 MST)是圖論中的一個核心概念,指在一個帶權無向連通圖中,邊的權重總和最小的生成樹。以下是詳細解釋:
假設一個圖有 4 個頂點,邊權重如下:
( A-B: 1 ), ( A-C: 2 ), ( B-C: 3 ), ( B-D: 4 ), ( C-D: 5 )
其 MST 的邊為 ( A-B ), ( A-C ), ( B-D ),總權重為 ( 1+2+4=7 )。
通過以上算法和性質,MST 在優化問題中具有廣泛的理論和實用價值。
