ACOGNA2: A novel algorithm for maximizing accuracy in global network alignment

Proteins do not independently work, they interact with each other. Their interactions are modelled by protein-protein interaction (PPI) networks. PPI networks alignment problem has great significance in the biomedical field and has attracted the interest of many researchers. This article introduces a new algorithm called ACOGNA2 to global aligning the PPI networks. Experiments demonstrated that the proposed algorithm outperform the state-of-the-art algorithms.
