Maximum Agreement Subtree63, or known as MAST is a distance metric used to compare phylogenetic trees, specifically the similarity between two trees. This metric measures the distance between two trees based on the size of their maximum agreement subtrees. A maximum agreement subtree is a subtree that appears in both trees and has the maximum number of nodes. The MAST distance is the difference between the total number of nodes in the two trees and twice the size of their maximum agreement subtree. In other words, it measures the number of nodes pruned from one tree to obtain the other.
