Sorting by Block-Interchanges and Signed Reversals
A block-interchange is a rearrangement event that exchanges two, not necessarily consecutive, contiguous regions in a genome, maintaining the original orientation. Signed reversal...

A more efficient algorithm for perfect sorting by reversals
We describe a new algorithm for the problem of perfect sorting a signed permutation by reversals. The worst-case time complexity of this algorithm is parameterized by the maximum p...

Approximating Reversal Distance for Strings with Bounded Number of Duplicates
For a string A = a1 . . . an, a reversal ρ(i, j), 1 ≤ i < j ≤ n, transforms the string A into a string A = a1 . . . ai−1ajaj−1 . . . aiaj+1 . . . an, that is, the reve...

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...
