Abstract
Storage structure alternatives exist for structuring symbol trees. Sequential structure is used in Trie and linked list structure is used in Doubly Chained Tree. A model of hybrid tree structures is presented which employs storage structures at levels where they are most efficient. The model parameters are determined by the densities of key components. A related hit ratio problem is solved so that these densities can be estimated. Analyses are given to determine appropriate tree structures from the model.
