Designing weights for quartet-based methods when data is heterogeneous across lineages

no code implementations27 Feb 2022 Marta Casanellas, Jesús Fernández-Sánchez, Marina Garrote-López, Marc Sabaté-Vidales

Second, we test and compare the performance of several quartet-based methods for phylogenetic tree reconstruction (namely, Quartet Puzzling, Weight Optimization and Wilson's method) in combination with ASAQ weights and other weights based on algebraic and semi-algebraic methods or on the paralinear distance.
