一棵有根树是可重构的,如果它是由它的多个有根子树(具有相同的根)的集合确定的,这些有根子树是通过删除多个顶点而得到的。我们确定哪些有根树是可重构的,并且展示了如何使用它来研究无根树的可重构性。
A rooted tree is ℓ -reconstructible if it is determined by its multiset of rooted subtrees (with the same root) obtained by deleting ℓ vertices. We determine which rooted trees are ℓ -reconstructible for ℓ ≤ 3 and show how this can be used to study reconstructibility of unrooted trees.
