Witryna24 lis 2004 · Trees with more rapid trait evolution, which means higher speciation-rate heterogeneity across lineages, produced highly imbalanced trees after extinction and recovery, when subjected to random extinction. This is the result most consistent with observations for the dorid nudibranchs. WitrynaBalance and imbalance. Unfortunately, use of a binary search tree does not guarantee efficient search. For example, the tree. is a binary search tree in which search proceeds the same as in a linked list. We thus are forced to consider the balance of a binary search tree. Informally, a balanced tree has subtrees that are roughly equal in size ...
