Fig. 5From: Reconciling multiple genes trees via segmental duplications and lossesAn illustration of one pass through the algorithm. The species tree S is left and \({\mathcal {G}}\) has two trees (middle) and partial mapping \(\alpha \) (labels are the lowercase of the species). Here \(\alpha \) is in a clean state, and the algorithm will pick a lowest minimal \(\bot \)-node (white circle) and try to map it to, say, H. The forest on the right is the state of \(\alpha \) after applying this and cleaning upBack to article page
