Efficient Exact and Approximate Algorithms for the Complement of Maximal Strip Recovery
Given two genomic maps G and H represented by a sequence of n gene markers, a strip (syntenic block) is a sequence of distinct markers of length at least two which appear as subseq...

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...
