本文提供了一个关于 Bock 1971 年最小成本树（arborescence）问题的教程。通过提供结构化重构，它阐明了该算法最初被认为晦涩的 Algol 表示。这种重构用显式状态组件替换了临时的标签更改，确保了 Bock 原始候选选择和解决方案的保留。 AI

- Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
- AI-industry relevance
- Low
- Off-topic or adjacent — cluster remains reachable but doesn't surface in AI-industry rankings.
- Story freshness
- 44 days old
- Aged out of breaking-news scoring windows; ranking reflects the durable signal from the full source set.

Bock算法求最小有向生成树的简明教程及结构化重构
arXiv:2603.27530v2 Announce Type: replace Abstract: Bock's 1971 algorithm is an exact primal--dual method for the minimum-cost arborescence problem, but its Algol presentation obscures the interaction of its maintained arrays and label-directed control flow. We provide a self-con…
