%A Ngoc Ha Tran %A Xuan-Huan Hoang %T ACOGNA: An Efficient Method for Protein-Protein Interaction Network Alignment %X Protein–protein interaction network alignment enables us to identify orthologous proteins, predict protein functions and build evolutionary relationships of species. This article introduces an algorithm for global alignment of protein- protein interaction network based on ant colony optimization (ACO) method. The experimental results offer outstanding advantages of the proposed algorithms. %D 2016 %L SisLab2371
