Chvátal–Sankoff constants

The Chvátal–Sankoff constants are a pair of important constants in the field of computational biology, specifically in the area of phylogenetics. They relate to the study of the evolution of species and how genetic sequences of different species can be aligned to identify evolutionary relationships. The constants, denoted as \(c_1\) and \(c_2\), arise in the context of the multiple sequence alignment problem.
