UpdownDistance

UpdownDistance computes the Updown distance to quantify topological similarity between a query tree and a data tree for structural searches in phylogenetic databases.

Key Features:

• Structural search capability: Searches for trees that are structurally similar or approximate matches to a given query tree within phylogenetic databases.
• Topological closeness measurement: Quantifies the extent to which topological relationships of two phylogenetic trees align by identifying similar structural patterns between the query tree and a database tree.
• Efficiency and filtering techniques: Incorporates filtering techniques to improve search efficiency for large phylogenetic databases.
• Algorithmic versatility: Supports both rooted and unrooted trees and handles weighted and unweighted tree scenarios.

Scientific Applications:

• Evolutionary biology comparisons: Enables comparison of phylogenetic trees to identify relationships among species or genes across large databases.

Methodology:

Algorithms measure tree similarity based on topological structures and support both exact and approximate matches, with experimental evaluations comparing their effectiveness to existing tree metrics.
