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...

What Makes the Arc-Preserving Subsequence Problem Hard?
Abstract. Given two arc-annotated sequences (S, P) and (T, Q) representing RNA structures, the Arc-Preserving Subsequence (APS) problem asks whether (T, Q) can be obtained from (S,...

Improved Algorithms for the K-Maximum Subarray Problem for Small K
The maximum subarray problem for a one- or two-dimensional array is to find the array portion that maiximizes the sum of array elements in it. The K-maximum subarray problem is to...

On the least median square problem
We consider the exact and approximate computational complexity of the multivariate LMS linear regression estimator. The LMS estimator is among the most widely used robust linear s...
