The deck of a graph G is the multiset of cards {Gv:vV(G)}. Myrvold (1992) showed that the degree sequence of a graph on n7 vertices can be reconstructed from any deck missing one card. We prove that the degree sequence of a graph with average degree d can be reconstructed from any deck missing O(n/d3) cards. In particular, in the case of graphs that can be embedded on a fixed surface (e.g. planar graphs), the degree sequence can be reconstructed even when a linear number of the cards are missing.

从部分甲板重建稀疏图的度数序列

G的牌组是多组牌{G-vv(G)}. Myrvold (1992) 表明,图的度数序列n7顶点可以从任何缺少一张牌的牌组中重建。我们证明了一个平均度数为d的图的度数序列可以从任何缺失的甲板上重建(n/d3)牌。特别是,在可以嵌入固定表面的图(例如平面图)的情况下,即使丢失了线性数量的卡片,也可以重建度数序列。
