Fig. 1From: Efficiently sparse listing of classes of optimal cophylogeny reconciliationsExample of two reconciliations \(\phi _1\) and \(\phi _2\) on the same input. For each reconciliation, we draw the parasite tree on the left, the host tree on the right; the solid edges represent the associations for the leaf parasite nodes; the dashed edges represent the associations for the internal parasite nodesBack to article page
