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

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...
