在树木的邻近地区

On the neighbourhoods of trees

Peter J. Humphries, Taoyang Wu

摘要:

树重排操作通常在系统发生树的空间上引入度量。这些度量的一个重要性质是邻域的大小,也就是说,从给定的树中进行一次操作的树的数量。我们提出了一个表达式的大小的TBR(树平分和重连)附近,从而回答了一个问题,首先提出的组合学年鉴,5,2001 1-15。

英文摘要:

Tree rearrangement operations typically induce a metric on the space of phylogenetic trees. One important property of these metrics is the size of the neighbourhood, that is, the number of trees exactly one operation from a given tree. We present an expression for the size of the TBR (tree bisection and reconnection) neighbourhood, thus answering a question first posed in [Annals of Combinatorics, 5, 2001 1-15].
