A Lower Bound on the Transposition Diameter
Sorting permutations by transpositions is an important and difficult problem in genome rearrangements. The transposition diameter TD(n) is the maximum transposition distance among ...

Sorting Genomes with Centromeres by Translocations
A centromere is a special region in the chromosome that plays a vital role during cell division. Every new chromosome created by a genome rearrangement event must have a centromer...

A linear time algorithm for the inversion median problem in circular bacterial genomes
In the median problem, we are given a distance or dissimilarity measure d, three genomes G1, G2, and G3, and we want to find a genome G (a median) such that the sum 3 i=1 d(G, Gi...

Estimating true evolutionary distances under rearrangements, duplications, and losses
Background: The rapidly increasing availability of whole-genome sequences has enabled the study of whole-genome evolution. Evolutionary mechanisms based on genome rearrangements h...

A Heuristic for Phylogenetic Reconstruction Using Transposition
Abstract—Because of the advent of high-throughput sequencing and the consequent reduction in cost of sequencing, many organisms have been completely sequenced and most of their g...

Counting All DCJ Sorting Scenarios
In genome rearrangements, the double cut and join (DCJ) operation, introduced by Yancopoulos et al., allows to represent most rearrangement events that could happen in multichromos...

Sorting by Weighted Reversals, Transpositions, and Inverted Transpositions
Abstract. During evolution, genomes are subject to genome rearrangements that alter the ordering and orientation of genes on the chromosomes. If a genome consists of a single chrom...
