Generalized tree alignment
In computational phylogenetics, generalized tree alignment is the problem of producing a multiple sequence alignment and a phylogenetic tree on a set of sequences simultaneously, as opposed to separately.
Formally, Generalized tree alignment is the following optimization problem.
Input: A set and an edit distance function between sequences,
Output: A tree leaf-labeled by and labeled with sequences at the internal nodes, such that is minimized, where is the edit distance between the endpoints of .
Note that this is in contrast to tree alignment, where the tree is provided as input.
