Abstract
Optimizing a bitmap data tree and a corresponding lookup operation in the bit map data tree may be provided. A number of branches for each search node of a data tree may be counted. The data tree may comprise a plurality of search nodes. Then an optimum depth for the plurality of search nodes may be identified based on the number of branches in the data tree. Next, a hash node may be added to replace a search node of the data tree when a number of branches for the search node is greater than the identified optimum depth.
