A practical approximation algorithm for solving massive instances of hybridization number for binary and nonbinary trees
Leo van Iersel, Steven Kelk, Nela Lekić +1
Reticulate events play an important role in determining evolutionary relationships. The problem of computing the minimum number of such events to explain discordance between two ph…
