Figure 2. — Presents the 2 networks (Network 1 on the left side and Network 2 on the right side). Blue nodes are the aligned pairs. Green and red node pairs are the candidate pairs for alignment as they have aligned neighbors. The node pair with green color (u₂, v₂) has a score of 2 (due to 2 aligned neighbors) while the node pair with red color has a score of 3. According to the Stage-3 algorithm, the red nodes pair will be aligned first and then the green nodes pair will be aligned. The nodes u₇, u₈, and v₇ will not be considered as candidates for alignment as they do not have any common aligned neighbor.
